So I've been seeing this guy for like 3 months now.We hang out alot,you know do stuff couples do:movies,dinner,going out name it.Ofcourse we have sex..alot.He has introduced me as his girlfriend to his friends despite the fact that we've never talked about dating.We've never said "I LOVE YOU" to each other too.Sometimes I feel like we are just wasting each other's time but then he is always there when I need him.I'm not sure if I'm just afraid of being alone or loosing a friend.HELP
