Breakups

Do you ever truly get over a breakup? Specifically one that you have children involved with? I have a one and two year old and it’s been a year that we have been broken up. I find myself missing him, and I don’t truly know why. He was abusive, a cheater, and a liar. As of today, he doesn’t help at all with the kids. He blames me for everything and states because I called the police when he beat me pregnant as “giving him a record” and now he wants nothing to do with me or our children. I feel bad most importantly for my children, who didn’t ask for this. I remember the day he walked out the door and I knew in my heart things were never going to be the same again. Sadly, I don’t know why I can’t move on, and why I blame myself for everything.
