I've posted a few times about my ex and I splitting due to his alcoholism and abusive manner as a result. He literally went online plus met another from work so was seeing several people very quickly and rushed into various relationships. I just feel very easily replaced. I didn't want him to pine but may be at least attempt to fix himself and instead he has women fawning over him and having sex, whereas I'm just with my kids. Usually I'm ok but sometimes I see or hear things from him which makes it obvious and it really hurts. How can I get over this feeling, I'm trying so hard.
