I've been dating a guy for about 10 months now but were not exclusive. we hangout atleast once a week and talk everyday, I've met his best friends and even his sisters, to his friends obviously I'm just someone he's dating and his sisters I'm just his friend. I'm confused! I really like him and from what he tells me I know he does too but at the same time I can't help to wonder why em I not his girlfriend? I want to ask him but I'm not sure how. We've both been hurt in past relationships but c'mon we have to move on right!

If you haven't felt it by now then its not there. You push the issue and if it goes your way, then be prepared to have a crash landing along the way!
Accept it and get over him. When he realizes he has lost you he can only do two things. Go on his way or work alot harder to win you back. Its all about the chase. If it comes to easy there is no reason to work hard to keep it. Just don't play any games. Get over him and move on!!
