Then he is a real idiot.
maybe they want to dump the other girl??? maybe they like you??? they could be joking... but i doubt they would be.
be hotter than her
Tell him the truth.
You do not WANT him if he already has a girlfriend. If he can be taken awy from her so easily, he can be taken away from you just as easily.
No, it is very wrong.
ask him, or ask his friends
If he "loved" you more he would break up with his girlfriend to be with you.
absolutely
I would advise to speak to this other girl first, and see if she really said that, or if the guy is just trying to play both of you. If the guy tries to stop you from talking to her, refuse the date, because that is a sign that the other girl really doesn't know.
You can try telling his/her parents.
Say yes. Duuh
uu wait till one of them dumps the other then uu ask the guy out : )
