My ex is making my anxiety worse throughout this pregnancy

I don’t know what to do girls 😢 I’m 7 months pregnant and my daughters father and I aren’t together like like not together to the point that I have a restraining order against him. I decided that I would unblock his number in case of any emergencies or if he wanted to know if the baby was ok (stupid I know I was feeling guilty I guess) so anyway today he texted today and asked if everything was ok and I just said fine I mentioned that I was thinking about other names for her and if I came up with a different one I’d let him know and he basically said that we would have to talk about it to which I replied that “we” don’t have to talk about anything (when we broke up he chose to leave at 4:30am and then also said that I should get an abortion because we weren’t going to be together) he hasn’t been here for 6 months of the pregnancy and it just drives me crazy because like yes he’s her father but you haven’t been here and you chose to leave so in sorry if I feel like yes I can pick her name without you he doesn’t know it yet but she won’t even have his last name and that’s gonna be another huge issue but with how he left everything he doesn’t deserve that right in my eyes. Ladies am I wrong for any of this? What should I do? Like this just makes my anxiety worse by the day.
