Really need some advice bad.... plz help?

I had a fight with my b/f but he did come over thursday which was nice, he acted sweet to me. He didn't stay long cause he had to work all night. Friday night I spent the night at his house and we kind of ended up getting drunk. We hung with his other roommate and did whatever. But of course, he had his snippy attitude for a good while till he got tipsy then he was nice. We went to sleep very late and he did actually hold me some. Anyway this morn he was very grumpy and hardly wanted to talk to me. Whne I ask what's wrong you look upset he freaks and says stuff like "If I wanted you to know then i would tell you. I told you i have issues and need to think them out but i can't when I have you pestering me". And I said i was just asking cause I cared. So he gets up mad. So then tonight i was with him, and I had to take his roommate up the road for a few mins and my b/f got so mad at me and said just don't come back. I'm like wtf is that about? He said you gonna talk bitchy to me then he was gonna be a a** back. he said take him then, go hang with him then. Sounded totally jealous because his roomy has been all talkative to me and stuff. But he got over it when I came back. After a few we was on the porch smoking a cigarette and I asked him, seriously why you so snappy at me and he chewed my head off. And I said ya know, i really do care for you. And he said ok hush :( he said he doesn't want to talk about our relationship. I'm getting to where I don't know what I'm gonna do. I love this man, but at the same time I hate how he's been acting..... me thinks I need advice... I don't want to lose him because he really is a good man, when he's not all pissy like this past week... anyway, thanks :(
