Sleeping with my baby daddy

So I’m pregnant rn and tithe father decided he didn’t wanna be involved and decided to move to 5 hours away for “work “ I think it’s bs but whatever he told me he never wanted to talk to me again but text me once a month asking how I am and then never replies like I don’t understand why he does that anyways last week he messaged me and asked me how I was doing and I replied he told me he was in town and I asked if he wanted to see me and he did so I went over we slept together I spent the night and he went back the next day to wherever the hell he’s staying he kept saying he missed me while we were having sex which made me upset Bcz he is the one who chose to leave and the one who blocked me and took me off all social medias if he missed me why wouldn’t he just text me I don’t understand I feel like maybe he feels somewhat guilty and that’s the only reason he still acts like he cares idk we haven’t talked since that day it’s making me sad Bcz I miss him and I feel so fucking stupid
