Need advice

Lauren
Okay so this guy wants to hangout with me before he leaves for college. I mean he's really nice and as helped me through things. But he confessed his love for me when he was loopy after getting his wisdom teeth removed. I also have a bf which he knows I do, but he just wants to hang out as friends. 
I don't really wanna hang out w him just because we aren't that close so it's kinda awkward. But I don't want to say no and be mean.
Idk whay to do. He's been a really good friends to me but I dorm want to hang out
Any advice ???
