So I am currently seeing a man who I absolutely love and he adores me. I am 21 weeks pregnant and we have been together since I was 4 weeks pregnant. He adores our son also. My sons bilogical father has not been there once. He is aware I'm pregnant and we do communicate civilly most of the time. Recently though he's been being a complete add about my SO. He keeps saying things like "well if SO is there I guess he's his father since thats what you want" or "I'm not going to be around if SO is there" "I'm not going to the ultrasound if SO is there" and the best is "I'm not even sure he's mine I think your lying". The last one hurts. I don't sleep around and I am a 100% he's the father. When I try to make things right or make things ok he gets mad and irritated saying things like "I don't have time" "I'm working" "I'm tired". I feel like these are all excuses and he just doesn't want responsibility. When I brought up him signing over rights he threw up his hands in defense and got REALLY mad saying how I just wanted him to sign over rights so SO could adopt him etc. etc. Yes that is why but i have NEVER once told him this. I'm so sick of being caught in the middle. I'm not putting the bio fathers name on my sons birth certificate and my son will have my last name. My SO is getting fed up with him also. He has never contacted my SO. However my SO has seen me cry over this man calling me a worthless excuse for a mother (which the bio does often). The bio has 3 other sons and is living with one of the mothers of 2 of his sons and claims theres nothing going on. I'm so sick of this. He's mad because I'm in a happy HEALTHY relationship. How do I get out of this sick cycle...I feel like this is abuse emotionally. I can't take him saying the things he does, making me look like a liar and making me feel like a bad mother. How would you handle all of this?
