I agree, with JC in that some people don't know how lucky they are, as my boyfriend works away (Germany), so like I haven't seen him for four weeks so far, and he's not on leave again til end of next month (SOB!!) But I mean it in a different way I think, coz the OP's boyfriend doesn't know how lucky he is! My bloke would love to always be at home, when he's a 2 minute drive away, and it's so hard to be away from eachother, which is why it always amazes me when people don't appreciate how easy they've got it! I'm not saying he should spend 24 hours a day with you or anything like that, but he should decide if he wants a relationship or just another mate, coz that sounds like what you are atm. I am nearly 20, and my bf's nearly 21 and we have got a serious, long-term relationship, but even if I was with someone else, group dates twice a week just wouldn't be good enough!
Talk to him, tell him what you want from your relationship!!
