Ok my fiancé has a 3 year old son which I have been in his life when he was about 2. Anyways year and a half later I'm pregnant. We have a little girl who is 1 now. So my fiancé wasn't around for the 1st year of his sons life due to BM. 5 months into us dating right when we find out I'm pregnant BM wants to "co parent" all of a sudden. I was excited for my fiancé since I know how hard it was to not see his son often. The first 6 month of "co parenting" we're hell.
