I NEED HELP!!

Sabrina
The baby's father and I have broken up for about two months. Since we have broken up he has been causing so many problems, calling me names, stalking me at work and stuff because he wants us back together when I don't want to be him since he can't hold a job because he's lazy and spends money on useless things he does not need. He never really asked about the baby, he never wanted her in the first place, he wanted me to get an abortion and has said multiple times she's not his, never went to any of her appointments because he told me it was pointless and not important and then he would get mad because my mom would go with me. Well this past week he's been sending me rude messages saying that I'm a lying cheating deadbeat because I'm not giving the baby his last name and I'm not letting him be in the room when she is born. And now he's saying I cheated on him, with this man who use to go to high school with me but we never even really talked and we never hung out in the first place. He says the baby's probably not his so he wants a DNA test done because he's pretty sure the baby isn't his. I have never once cheated on my baby's father, my baby's father was the first and only man I had ever had sex with. And when me and the baby's dad were together I was either at work, school or at his house. I didn't have time to do anything else and my parents were my ride because I'm only 17 and I recently got my own car and license in Novemer. I don't even know if I want to tell him when she's here because it seems like he doesn't even want to be her dad. Should I tell him when she's born or wait until he finds out? She's not going to have his last name and I'm not putting him on the birth certificate either way, so he has no rights for her unless he fights for it. I'm just in the fence wether to tell him when she's born.
