Unhappy early pregnancy

I'm now 8 weeks pregnant, the father I basically you slowly finding out that he lied his way straight to my bedroom to my heart.... Told me so many lies and it's all coming out.... I totally never thought. I would be unhappy in my pregnancy..... I'm basically pregnant for somebody I really don't know.... and that hurts.... I found out he has a four year old child that I knew nothing about. This was before my time but I don't see you I keep the secret. He on child support for this child..... He doesn't beat me but he's been manhandling me. I have bruises, might as well just hit me..... I'm scared of what my future's going to be like... I never grew up in a broken home I don't want my child to either but I may not have a choice... Had both parents growing up I want the same for my kids one daddy all of them. I always said that, Lol guess not. Does it always work that way.... smh the most I can do it pray.....
