to QS: your gf tried to stop him as u've said, if she is not interested with the guy and she doesn't like him so whats the problem? I think your gf is 100% inlove with you to tell that she has a suitor like that in the house cos if not she will keep it secret and flirt with the guy, and also a piece of advice, try not to neglect your girl for her not to look to aggressive people like her housem8s.
