Lost in emotions

The love of my life and the father of my daughter who is due in December, left 2 days ago. He told me many many times i was going to be his wife and we would raise our daughter, and try for a son, and be successful and now that I'm 15 weeks 3 days, he says i cry too much and need to harden up and that he doesn't want to settle down yet. Really?! I have dealt with his mood swings, he did 17 months in jail and i stood by him the ENTIRE time, helped him when he got out. We were supposed to be a team! He tells me he still loves me a lot and that maybe one day we will get back together when he is ready to settle down but right now i am so heart broken. How can you be jist friends with someone you love? I don't know what to do with all of these feelings!!!
