I REALLY need help with this. pleaseeee read :( :(?

okay, well i was dating my boyfriend for over a year now and we've gotten into some pretty heated arguments which we typically resolved. i'm the type of person that likes to talk things out right away while he likes to completely get away from it all. we've broken up once before and after some time of not speaking very much we worked our way back up to being in a relationship. everything was going really great and we rarely argued or got into any confrontations. up until recently...the other day he was talking about how he chills with this girl once in awhile (this girl is also known for being a skank and i've always been a little uncomfortable with him hanging out with her even if it's just for a quick talk) typically the only time he really sees her is when she comes into his work but i dunno. all i really said was that she makes me uncomfortable but i trust him and we got over it. later that night we went out to dinner and saw this girl who happened to be friends with the girl he sometimes hangs out with and i pointed that out to him and he was like oh really i don't know her. when we sat at our table she came up and was like hey i met you the other night. so i got a little creeped out and started asking him about it. he got really defensive and upset that i would get upset over that cause he said he didn't recognize her and that they just came into his work. it got to the point where we left the restaraunt and drove back to my house. i asked him to come in so we could talk and he didn't want to at all. i got really upset by this and started crying saying i was sorry for bringing it up. he kept telling me to get out of the car but my mind shut down from being so upset that i couldn't get myself to get out of the car. after awhile i got out and he was still really angry and told me to leave him alone and that he needed space. i said that i didn't want it to leave off like that and he said we always fix our **** and then he left. i apologized the next morning through a text and didn't say anything after. i gave him space and didn't try contacting him until...i met up with one of my friends yesterday and he told me that my boyfriend said we broke up. i was really confused by this cause i had no idea that was the case. so i texted him saying that if he wanted to break up then i would much rather hear it from him than one of my friends. he replied by saying all these nice things about me but the other night was too much for him to handle. i said that i was having a rough week since i just got out of school and have some problems at my house and reminded him that he said we always fix our stuff. he said he needed a break and that he has too much stress in his life. and that's how it left off. i texted him once more asking if this is sincerely what he wants and that i wasn't going to say anything else to him and he didn't respond. and that's the last attempt i made. i don't know what i should do at all. everything was fine up until this point, we both had really shitty weeks and i thought we could get past this after a couple of days. please give me some advice for what to do, i'm at a loss.
