I have plenty of female friends and generally am not intimidated by them. But when i want to move beyond friendship and really get to know a girl i freeze up totally. I find myself unable to talk to them beyond superficial stuff and can't think of ways to get to realll get to know them and end up being 'friendzoned'. It makes me feel totally useless around women and i get so frustrated at myself. Whats the best way to get over this and get to know women better?
