Really annoyed with bf

I'm so annoyed and a little hurt by my boyfriend. He doesn't go out much, and I honestly don't like when he does. But last time he did he told me he'd be home before dark, and he even called me when he was leaving and doing what he said he would. Well tonight he had a beer in his hand then just left. Didn't tell me anything. I texted and asked all he said was "having a few beers with (his friend) why." I told him then he didn't say anything so I asked if he went to his house or out he told me he went out, then texted me a few times but I didn't even respond. I'm so annoyed because he never takes me out anywhere but perfectly capable of going out with a buddie. Let alone he doesn't spend time with me anymore for a while now but again perfectly capable of going out with a friend. And tonight I was kind of hoping we'd have sex because we never do anymore. But of course he goes out instead so that's a definit no for sex. Idk what to do. If I be a bitch because I'm pissed he'll just not ever tell me anything and be acomplete Dick about going out, but I'm really not happy with him. And I know he probably gets the hint. I'm just super frustrated I do all this stuff, work 6 days a week, go to school, expected to do all household chores, get bitched at if I don't do something right away, I'm not 21 yet so I can't go to the bars, but I drink at home(I'm 8 months away from 21)but I don't have friends to even drink with besides one who hardly ever hangs out, and my boyfriend and his friends. I'm all work and no fun, not really by choice. But he can do whatever and it's no big deal. I'm just sitting home alone having nothing to do besides homework and hang out with our 3 dogs. Just like every other night.
