@yaharise This resonates.
I was not perfect, by any measure, but my ex was ruthless when we did finally split. From my perspective, she essentially replaced me with an old boyfriend. She then proceeded to demand exactly what she needed for herself in order to build a new situation, regardless of the cost to me or the kids. It was really eye-opening for me.
For a long time after, I was super resentful. I wanted only bad things for her, for her new relationship, etc. I remained connected to her social media in order to see photos and such of the kids (we share 50/50 custody), but that was a double edged sword, because I also had to see glimpses of her new, happy home.
I wanted her to be unhappy or for her relationship to fail. I imagined any such failures would be proof that she had been the problem, and not me (of course, the “problem” had been the both of us).
Eventually I got past all of my petty resentments. I began to see that if she was happy and doing well, then that was good for my kids. And I began to understand that, while I had my part to play in the failure of our relationship, neither of us was solely to blame. And the failure of the relationship did not mean that we were each failures as people.
Also, I began to appreciate that most social media façades are just that - a carefully crafted presentation of life, and not remotely real. And this was true for her. It turned out that her new life was not perfect. She and her new husband are happy enough, but they bicker and argue and disagree, just like everyone else.
And I realized that the life they share, the life that seems to be the life she was after, would never have made me happy. Which explains why we didn’t work, and also why things seem to work for them.
