I know exactly how you feel hun, I cried almost everyday my last trimester

It is rare to find a man that can handle having a child! Stick to your beliefs, having a child is a beautiful cultivation and you won't be disappointed. My daughter has made me a better person and I have never felt a love so pure, positive and constructive. I know it's hard but you need to get away from this man ASAP! The stress from this relationship could have devastating consequences this early in. My advice is to spend time with family and/or friends. If you're close with your mother maybe it's best you stay with her or she stay with you, find someone you trust and that is positive to help you through this difficult time and take a bit of the load off
My story;
My BF had had a child from a previous relationship but was adopted by the step father last year. When I told him I was pregnant he wasn't upset nor was he overly happy, he had expressed some of his stresses but insisted that this was his chance to do it right with someone he loves and that loves him. About 3 months into it he changed! He started going out and getting wasted; strippers, clubs, bars. I later discovered him cheating on me with someone we know, he lied and drank almost constantly. The day before our daughter was born he told me that he resented me for getting pregnant despite a tissue build up in my cervix, that I was an inconvenience, he didn't want this child, that he didn't love me, and the reason he lied to me and drank all the time was because he didn't care about me. About a week after our daughter was born we had the "talk", he apologized and told me he wanted to work on it, he then made a bunch of promises he has since failed to keep. I'm scared, embarrassed, sad, anxious, angry, feel hopeless, and I don't think the hormones have worn off yet because expressing these emotions to him rationally is still not possible.
My mother helped me cope through most of this but the only advice she could offer was for me to stay with him and deal with it for our daughter's sake, "you'll get used to it" she said. I stuck it out and stayed. For my daughter's sake I am looking for a place of my own, we both deserve to be happy and live in a healthy environment.
I'm telling you now, not like you don't know, it's going to be hard. You will feel all of these wounds like they're fresh everyday all you can do to prep yourself is to make sure you keep yourself/mind occupied. Meditation and yoga help a bunch, funny movies, cooking, good friends, lots of chocolate and/or cheese. If you ever need anything, I'm here. I also live in Canada, in Calgary, AB.
