my first impression on a gr8 looking guy would be this, I guess. I'd almost be sure he is a player, as in this world, good looks are a prized possession, those who possess them will be invariably made aware of their gifts and more often than not, they misuse it. In a while, they start considering themselves "superior" to their peers and behave rude. well, again this is my observation in most of the cases. I do agree, there are really good looking people who are also beautiful inside, but that will take time to discover.
Well for a start they are using her! I think you need to have a chat to her, not in my words but something of the lines of, if you continue to do this you will only get hurt! I think in her eyes for that split hr/however long, she feels loved in away. She needs to be told doing things like what she does can only give her a bad name, and that is why she attracts these men!
Well, I would assume that a good-looking guy is a player b/c of the fact that so many girls are wanting him. I doubt too many guys would turn that down if they were in that position. So I'd be really wary about trusting him b/c he's probably cheating anyway.
Some might - but in general girls and guys associate beauty with positive qualities (honest, smart, funny). The beauty with vice equation is out there, but is usually set aside for a particular person if he likes a girl.
