A: No it isn't wrong. At all. I know I'm not a girl but I couldn't help but read this. 'Sides you need an opinion from the opposite sex. It isn't wrong to dump a guy because he won't like you for you.
A: Some guys (me personally so I know this) are good at the very beginning. Then they get nervous and you just need to either break through his shell or decide if it isn't that and find out what else might be wrong.
A: Well personally I am not sure how to reply to this. Only thing I can really say is if you don't like the you now you have to put something into CHANGING it.
