Selfish boyfriend

I’m currently 15 weeks Prego.. & my boyfriend & I just had sex. He definitely finished & I didnt. I go take a shower come out and tell him I want to finish after. (I took a shower right after Cause he came inside of me & I hate waiting till I’m finished) so he tells me after you give me head. I’m like ok, so as long as I get his dick to stand up he will finish wtf he just started right ? But mind you, we are in the living room cause we don’t have our own room yet. Everyone is supposed to be sleeping. But my little sister goes into the kitchen which is next to the living room during. She didn’t see us but obv I was very paranoid after. & he just says I guess were done here. Like what? I told him I wanted to finish he just ignores me. Tell me how I look over & hes masterbating. Like immediately I just start crying. I don’t mind if he watches porn or masterbates but the fact that he tells me “well at least pornhub did me good” & goes right to sleep. Like really ? I didn’t even finish. & he got his nut twice.. idk what to do. He’s just selfish af.
