Dumpers, do you want an apology?

I'm 2 years out from a relationship and continually having deeper and deeper recognition that my trauma and lack of ability to deal with it was the entire reason our relationship failed. It caused me to create a lot of chaos and push-pull dynamics in our relationship. I feel like it's a big step for me personally to take ownership over that and that she deserves an apology and a reframe around things that I made her problem, or our relationships problem. But it was my problem.

She's in another relationship now and while I'm crushed about it I have no illusions that she will be coming back. I just want to apologize and take responsibility. We've been no contact for over a year and a half.

Would you want the apology or to be left alone?
