I think my ex changed because of me and it hurts to see him love another woman?

I didn’t have concrete proof but I had enough proof to believe that he betrayed me and I was devestated. The list of things he did to hurt me is long, but one thing that sticks out is that I remember him telling me out of anger that if I got pregnant he wouldn’t take care of the baby. He apologized later, but the damage was done that he would even say that- ithurt so badly to have something like that thrown in my face. The current woman he is with has kids that aren’t his, so it’s like a slap in the face towards me. It never stopped hurting that he threatened to abandon me with a baby if I got pregnant from being with him. When he did apologize he seemed genuinely sorry so I forgave him. But now to see him with her it feels like it was me specifically that he just acted like that towards. But despite making a comment like that he seemed to trust me and love me. He cried to me, he confided in me, he seemed to love me. But after he betrayed me I tried to convince myself that he never cared. Some years after we broke up he hmu trying to make up. I didn’t take him back. His tone on Facebook seemed to change after that. He started to talk as if he had sense. He didn’t joke about hurting people or being a liar. He seemed to then suddenly value being a good person. He even made post saying he was going to change and be a better man. Then he got with this new girl and seems like those changes stuck. He probably came into the relationship a more mature man. I have no way of knowing for sure, but I feel like he made his decision to be “better” all of a sudden based on me not taking him back and holding him accountable for the things he did. He seemed like he just suddenly flipped a switch after that. And even though it’s a good thing it hurts. Because I feel like I had to sacrifice and take the loss despite how hard I did love him and how hard I tried with him in order for him to actually change. I feel like I had to be the test dummy
