Quick question though!

This my 2nd son with the same guy. Our first son is 8yrs old. Me & him broke up during my first pregnancy b/c he was very annoying to me(hormones). We decided to get back together after 7yrs & work things out, I got pregnant AGAIN(current) & this has been the worse pregnancy ever up til my 3rd trimester. First-second I was severely sick with this baby(morning sickness, spitting,etc the whole 9yards). And all he did was complain complain complain, cheat, lie, & make excuses...so eventually I got fed up & moved out. After I left he wanted me to come back & was all sorry & shit but I was totally over the whole situation b/c that's when I needed him most & he failed me several times. So fast forward To beginning of my 3rd trimester my doctor wanted me to stay off my feet until the baby was due b/c I'm so swollen(5ft 223lbs🙄) & he didn't want me to fall again....but remind u I live 3 1/2hrs away from my doctor after moving out from with the father so when I did come to town I stayed at his place but of course he had to be on some disrespectful shit talking to other girls on the phone while I was there so I said something to him about it & his response was if u don't like how I do shit around here u can leave....so I definitely left ✌️ but anywho now it's time for the baby & he wants to be in the room when I have my c-section & wants the baby named after him😂 but haven't bought shit @ ALL....at this point I don't want any dealings & just wondering will I be selfish to keep him out the room a 2nd time?
