Feeling lost and alone

Jessica
I found out 3 weeks ago that my boyfriend of 2 years has been trying to get his ex wife back. I know this bc she sent me the text messages. Now I know she did this to clearly mess things up for us, but if he wasn't doing me wrong, there wouldn't have been anything to send me. I've been nothing but amazing to this man and all his ex wife does is make his life difficult and keep his daughter away from him. I can't believe he did this to me! I'm 7wks pregnant as of today and I told him I can't be with him. I don't trust him and I don't feel that he loves me. I tried to get past everything bc I'm having his child, but I'm terribly broken hearted. This baby was planned. Every time we made love all I could think about was how my child would be created from all this love, but I guess all the love came from me. What hurts the most is I recently asked him if after our years of being together and living together am I now your family? He didn't give me an answer, but texted his ex wife saying he wants his family back. I never thought I'd be a single parent... Especially one even before my baby arrived. I don't know if I'm wrong for leaving him, maybe I should just stay for the baby sake. I'm just so lost. So sad and depressed. I can't believe this is my life.
