I've been wondering a lot what we are and what he is after. I know what I want and that's something serious. I know a guy can act like a boyfriend but leave right after you sleep with him or people who ended up married after a one night stand. He will stick around whetever we have sex or not if he wants to be with me it's not about sex.. I really can't tell if he just wants sex but since he's been sticking around for a while now I just don't think that he wants to sleep with me then leave but then again you never know. Are there any signs that tells you if he wants to keep you or if he's not serious? I don't want to waste my time and end up getting hurt but I don't have the guts to ask him what he wants.
