Why can't my sons dad just come and do a normal visitation with his son without asking me if I miss him, if I think about us, is there a chance we can get back together, will I have sex with him and the question of the day : will I take him back if he gets a vasectomy ! This guy is 43. I broke up with him when I was 36 weeks pregnant. I told him NO to all questions. He won't give up tho. He has harassed me with these questions since January when I broke it off. He hasn't seen his son in 6 weeks up until today. I was so happy when he left.
