Nobody wronged anybody. The love is still there. And it still has to end. That combination is its own particular kind of awful, and the usual advice about blocking their number does not touch it.
Most advice about letting go assumes somebody was the villain.
Cut them off. Block the number. Remember how they treated you. Write the list of everything that was wrong and read it when you feel weak.
That advice works fine when it applies. Trouble is how often it doesn't.
Sometimes nobody was cruel. Sometimes the love was real, and it stayed real, and it had to end anyway. You're not trying to get over someone who hurt you. You're trying to put down someone you'd still pick up the phone for.

Why does it hurt more when nobody did anything wrong?
Anger's useful, that's why. It gives you somewhere to put the feeling. It organizes the whole thing into a story with a shape: they did this, so I left, so I am justified.
Take the villain out and the story loses its shape entirely, and all you've got left is the love itself, sat there with nowhere to go.
I've had three endings that each taught me a different piece of this (there were more than three, but these are the ones that did the teaching).
The first was my first great love, in college, both of us buried in pre-med. She left for medical school in the Caribbean and I stayed home, no longer on the medical track. It didn't end through conflict or betrayal, it ended through direction, and ultimately it was a mutual split.
Sometimes love doesn't end because it failed. Sometimes it ends because life moved, and the two of you moved with it in different directions.
The second was a woman who loved me with a devotion so steady it softens me to this day, the most selfless love I have ever been given. She was ready to root, to build stability for herself and her child, to have more children. I was ready to travel and see the world. Our love was real, and our souls wanted different things at the same time.
This one was different for a lot of reasons, but the ending is the part that matters here, because I was the one who ended it. And interestingly enough, it hurt just as much, if not more, precisely because I had to be the one to choose it. That is something I genuinely did not see coming.
There's a specific pain in wanting to protect someone and being the thing they need protecting from. Knowing the ending has to happen, and knowing it has to come from you.
The third was the one I call my almost forever. We were building a house together, spoke of and were days away from an engagement, and were planning for children. I'd spoken to her parents. We traveled the world together (shark diving in Hawaii, pyramids in Mexico, trains through England, her asleep on every long car ride while I drove). It was, in a lot of ways, a blend of everything the others had taught me, arriving right when I finally had some ground under my feet.
And it ended anyway. So what do you do with that?
If they were good to me, why can't I just be grateful?
Well, the truth is you can, eventually. Gratitude is real, and it does genuinely arrive.
What gratitude won't do is show up on schedule because you've decided it should. You can't skip ahead to the part where you feel philosophical about it.
After that first love ended, I had one of the biggest breakdowns of my life, in what I called a quarter-life crisis, at roughly twenty-six years old. After intense periods of grief, I ultimately ended up throwing myself into triathlons and marathons, running faster and riding harder and pushing further, in an attempt to just have some peace from the anxiety that flooded my body. Sixty miles alone on a bike genuinely is meditative, so I believed I was processing.
Looking back, I think part of me believed I could outpace heartbreak. That if I worked hard enough I'd get back to that feeling by effort.
Turns out no distance I ever rode got me closer. Every attempt just reflected back how rare that love had been. (Sixty miles is a long way to go to learn that.)
Grief is the reminder that love was present. Even when it is no longer in its original form, that love still exists. That's the actual shape of what happened, and running from it just means running.
How long is this supposed to take?
Unfortunately, and most likely, longer than you wanted it to. Probably longer than the people around you will have patience for. I don't say that to be negative, but rather to prepare yourself that at times the journey may be lonely.
With the woman I had to make the hard choice to end things with and leave, it took me years to fully digest it. As has been the case after all my relationships, I stayed single intentionally for a long period of time. Rushing into anything would have taken something away from a process I needed to honor. I had to come to terms with my own choice before I could love anyone else the way I knew I was capable of.
Nobody tells you that part of the timeline is actually a decision you make. The pain isn't. You don't get a vote on how much it hurts or how long it lasts. What you do decide is whether you let the grief run all the way through, or whether you paper over it with someone new and find it waiting for you in eighteen months, completely unchanged.
What actually helps
What reliably moves something for me is a loving-kindness meditation called metta. It's a core practice in Buddhist psychology, and it goes back a very long way. You send silent goodwill outward, including to the people tangled up in your pain. It sounds soft. Depending on your experience with meditation and this type of work, you might even find it "corny." It really isn't. Honestly, it's one of the harder things I've ever practiced, and one of the few that truly makes a difference in resolving the pain and bringing comfort.
Read it through first. Then close your eyes and say it out loud. Repeat as many times as you need to.

Start with the classic form. You say the same four lines five times over, changing who they are for each round:
> May I be safe.
> May I be healthy.
> May I be at ease.
> May I be free from suffering.
Swap the "I" for "you" as you work your way outward. Yourself first, then someone you love easily, then a stranger you have no feelings about either way, then the person who hurt you, then everyone. Hold each person in your mind while you say their round. Picture their face, one at a time, and let the words actually land on them instead of just running through the lines. Widening it like that is the whole point of the practice, because it trains your heart to do for a difficult person what it already does automatically for someone you adore.
The fourth round is the one people genuinely would rather skip, and it's probably the strongest one, because it's the one that carries the most pain more often than not. That's the round you say for someone who hurt you. It feels wrong at first, almost like you're letting them off the hook. But I promise you, you're not.
This helps you. It's not necessarily for them. It's for your peace and your closure, and whether they ever hear about it or not is entirely beside the point.
Beyond the classic, there are a couple of others you can do very quickly that are helpful as well.
If your heart is broken:
> May I heal gently.
> May I release what no longer serves me.
> May my heart soften and stay open.
> May I meet this moment with compassion.
For the one who hurt you:
> May you be at peace.
> May you find clarity.
> May your heart be free from suffering.
> May your path be guided by kindness.
For closing a relationship:
> May we both be free.
> May what was shared be honored.
> May the lessons stay and the pain loosen.
> May we each walk our path with grace.
That last one is the one for this situation. Picture them while you say it. It can be painful, and seeing the person in your mind while you speak the words aloud is the most important part of it.
What letting go actually means
It doesn't mean deciding you never loved them, and it doesn't mean quietly rewriting them into someone worse so that the leaving makes sense in hindsight.
It means stopping the argument with reality. Letting the love stay exactly as it was, and not forcing or demanding that it turn into something it cannot be now.
All of these loves opened a door for me to what love could be. Doors like that, once they are open, never fully close again. Whether we speak or not, I am still friends with and wish well upon all of my loves. I celebrate each of their successes, the families they have built, and the lives they have made, completely and fully.
So what does finished actually look like?
I can't know for sure. I'm figuring this thing out right alongside you. But one thing I do know is that it isn't indifference, and it is definitely not hate. It's just the end of the fight, and recognizing the completion of a cycle, one that has come to an end.
One thing I remind myself of in these moments is a line I picked up from a motivational speaker online. It is the idea of hope, spelled out:
H.O.P.E.
Hold On, Pain Ends.
