Honestly, can you see yourself living your life forever with this person? I don't think so. It's very cool of you guys to try and work it out together for your child. But trust me, it's better to have two parents who can be friends and get along then two parents together who can't stand eachother. You will just end up getting upset with him and it will most likely get worse. You two should probably sit down and talk about it.Unfortunately, with so much history one of you will get hurt if not both. But you can't use that as a scape goat. If you are trying to make something of yourself then you need to be true to your self.Good luck!
