I bet you must be blonde
dms, betting that
Blonde Goddess is blond seems to be a very risky bet
BG, we don't know the guy. Your friends don't know the guy either. You should make the decision alone and listen to nobody. Unless of course your friends know that you always fall for the wrong guys.
Everything beyond that is a generalization. He could be a nice guy or he could be a not so nice guy. The best thing you can do is to talk to him directly about this. By the way, the "Oh it will never work out" and Oh you know he probably has 6 girlfiends flying over to see him all the time" are possible. But the "Oh when he gets you, he will change and make you work 24/7 like a dog and will treat you bad" is ridiculous. Some guys can be players in order to get as many girls as possible. But they would not act in this way just to get somebody working for them 24/7 !!!!
