what do I do?(this is LONG)

Ok. So I am 32+5. I am in a predicament. The father of my baby is absolutely terrible to me. My midwife has been a doctor for over 30 years and she said I have been her toughest patient, only meaning because I've been SOOOOO sick. I've been in and out of the hospital. And since week 10 I've had a home nurse that comes every week and gives me a new iv. I get fed through my iv because I cannot keep any type of food down. The father never once helped me when I was sick (we did live together) he would play his Xbox and invite his friends over instead when I was losing tons of weight and constantly throwing up. He would make a MESS around the house and never clean up after himself and he would expect me to do it. He would even complain if I asked for him to get me a water out of the fridge because I was forbidden from walking unless it was to use the restroom. I eventually of course got tired of it and I moved out and moved in with my dad. Him & I have tried on and off. I have gave him numerous chances to fix his personal issues. (He never paid bills on time when he had plenty of money to do it, also stated before he lives like a pig, and he was disrespectful to me.) we tried working it out here and there and at one point we were doing excellent. I had came to his house for a date night and found on his phone him messaging his ex girlfriend sexual related things and I instantly left. I have no feelings for him anymore and I can honestly say he has made me hate him. I can't even express how many times I have tried with him. His friends and games are more important to him than our relationship. He claims he wants to be apart of this babies life, but I truly think he says that so he doesn't have to pay child support. He is a compulsive liar and manipulator. He makes EVERYTHIG a joke. I am not allowing him into the delivery room because I feel he will stress me out and make a joke out of it more than support me. My question is, knowing what you know, if you were in my situation would you give your baby his last name and put his name on the birth certificate? I am lost on what to do. I need some woman help. I have no family besides my dad. I am beside myself and need some advice please.
