someone help ( stealthed )

so me and my boyfriend were having sex today ( with protection ) but half way through intercourse i realised it felt a little different anyways i stopped and found out that he took his condom off. i pushed him away and started crying i know he only had it off for like 5 seconds untill i noticed but it was stressful. anyways so i was crying and he started hugging me and saying sorry and he started tearing up because he felt bad anyways i got up and went back to my house and didnt say goodbye to him. then he messaged me just before and said he was really sorry and he didnt think i would care because he was going to pull out bla bla bla. so now his really sad because he feels bad and his kinda acting weird

what do i do
