Narcissistic Father of Baby-to-Be

First of all I would kindly ask that if anyone has a negative opinion that is not constructive, do NOT reply, just disregard my post and keep moving along. I'm not trying to be rude, but I will react if something is negatively posted so I ask for common courtesy. 

This will be a lengthy post, but I ask that you ladies would tell me what you would do in this situation if it were you. 

I am currently almost 14 weeks pregnant and I have been in an off and on relationship with my boyfriend for a little over nine years now. We have had a very rocky relationship due to immaturity, infidelity, and trust issues on his part. However I do blame myself for sticking around, no need for anyone to point that out because I am pregnant now so it's a little late for that. I live in Michigan and I found out a day before he moved to Georgia with his family that I was pregnant. Before I found out, I thought he would be out of my life for good honestly because he was moving so far away and we've had a toxic, narcissistic relationship. I love him dearly and he tells me he loves me but has a long history of lying, craving attention from other females, and just being untrue behind my back but will be in my face like I'm the best thing that's ever happened to him and say how much he wants his family. I've pretty much been going through my whole pregnancy alone because he's so far away and I don't feel that I get the emotional support from him that I thought I would get especially being pregnant and he wanted this. I don't even get phone calls just texts to check up on me or for daily conversation. A week before I found out I was pregnant, he told me that he prayed I would get pregnant and no I didn't get pregnant on purpose. I just found out that I'm having a boy and he wants him to be named after him. This is our first child, no previous children for either of us. I personally don't like his name and don't really feel that he deserves for my son to be named after him because clearly there's no respect for me and what we had of a relationship and we aren't married so I never really thought to make my son a jr if I had any kids before marriage. My family and friends are also giving me hell about what I'll be naming my son (saying I shouldn't give him his first or last name, if anything make his first name my son's middle name) and of course have their opinions as to why, but I'm just kind of lost. Yes, it is his first child and first son but I don't want my son to grow up resenting me for naming him after his father once he grows up and sees how things really are for himself. I'm also not sure how present he will be and what type of father he's going to be. He says he plans to move back but I don't know...

I've been the best girlfriend I possibly could have been and given him chances on top of chances and even though I would like for my son to have a complete family, I don't think he will change his ways enough to mature and I also know that it's not healthy to bring a child into an unhappy relationship. I guess my question to you guys would be, would you name your son a jr if that was his first son and child despite what you have been through in your relationship or would you just name him whatever you wanted even though it may cause drama between you and the dad?
