Co-Parenting.

I am going to try not to make this a huge rant about having an ex, because I wouldn't want anyone to do that about me. My experience with co-parenting is a very good one compared to a lot of single moms I know. There are parents out the that don't get any help at all, there are some that don't have custody of their kids who should and then there are ones that don't ask for help and do it all on their own. My ex is a great dad. He loves his kids and would jump in front of a train to save their life is he had to, but when it comes to things that I ask for help with, it is difficult sometimes. I feel guilty when I ask him for anything including money help and for him to watch the kids. When we split up he had the thought in his head that because I chose to leave him, I also chose to be a single mom and he therefor had NO responsibility anymore. He told me this to my face. you can imagine the type of fight THAT caused. But lately, he is changing and realizing that he DOES have responsibility. BUT he still treats it like it's on his terms. I don't think this is right especially since he lives in the downstairs apartment...I don't know what to do to change things. We have talked a few times, but things get better for a bit then usually just go back to the way they were... I've decided to move away from him. Not very far but far enough that maybe he won't take for granted that his kids are right there.
