Search Results: he said he loves me but now hes distant

Ok so me and my ex had been dating for 7 months when we broke up. I am currently 7 months pregnant and we've been broken up for a month now. He woke up one day acting completely different and distant. I asked him what was wrong but he said he was just stressed. He started going out drinking and being with his family more. I finally understood that he had probably fallen out of love with me. I don't know why but he did, maybe another girl, family issues, etc. He told me that I make him unhappy and that we were better off without each other. We were together on and off for 3 years and had planned on getting married and having a baby. He picked a ring out and starting using pills to make his sperm count higher. He said he wanted to be in our daughters life no matter what. So he wants the child but the mother. I feel like an incubator. This wasn't unplanned and he seemed so happy when I told him. Then one after we broke up, he turned around and said he doesn't think y the baby is his. I NEVER cheated so this hurt very much. We lived together but he's moving out, putting his stuff in storage, and staying with his sister... isn't that a little much? He blames me for our breakup saying I stopped loving him, I changed, I started hating him, I never listened to his problems etc. I was never told about these issues at the time and if so I'm pregnant and my mind is constantly on the baby and work. I just wanted my pregnancy to be one of the happiest times in my life and to share it with the one i started it with. Now it's full of stress and heartbreak. I just don't understand what I did so wrong to have the man i was building a future with leave me...
