Another "be a man" post. Lets start off by asking what the hell feelings are? Girls dont share my feelings for them because I don't have feelings, and they very clearly do. Now I'll continue by asking why you're treating her different to any other girl you've liked? She might be prettier, nicer (whatever that means), but you still dig her, just like the other girls. Don't treat her specially, don't do everything she says, be extra nice (or even nice at all), hang on to her every word. She won't respect you for it. And what girl is going to chat to guys she doesn't respect (girls are weird like this). And I get pretty pissed off when girls come to talk to me, then get too intimidated to talk. I guess its a bit like this for supermodel girls too.
Chances are you've lost her, but in future remember - she might be good looking, but deep down inside shes just another person.
