So, my sons father and I officially broke up back at the beginning of may after he pushed me into the kitchen table. I told him weeks before I just wasn't happy and wasn't feeling it any more. I was completely uncomfortable living with him. He held me down before when I refused to have sex with him. He would go on the black market and buy weed (I don't do any drugs). I have no idea what else he was looking at. Im so done with his shit. I started dating a close friend back in may on the 10th. My sons father keeps insisting that I cheated on him with him and blah blah blah. The other day I went to talk with my sons father and he told me how he met a wife and husband and then later had sex with the wife, but the husband was okay with it. He met them online. God knows what else he is doing. I'm done. I'm not putting his name on the birth certificate. He can come visit my son in the hospital but when he finds out he isn't on the birth certificate he is going to be pissed. I'm giving my son my last name. And I'm circumcising him too. I am also going to court for full custody. I don't need my son around negative influences like him.
