I completely understand so much what you are going through. My x has me feeling the same thing. The only thing different is my son is 3 months old. I watched my x with my son this evening at my house and now I sit here crying because he left. For those few hours, I felt like a real family, the family I want to have so bad. My x didnt cheat on me, he claims he just fell out of love when we found out we were pregnant. I wish there was something I could tell you to help you through this painful time, but the only thing I can offer is to let you know I am going through the same thing.
