ask him, or ask his friends
be hotter than her
You can't make a girl jealous only when you know the girl likes the guy. If you know that the girl likes the guy but already has a girlfriend, then spend more time with the girlfriend that the guy already has and then laugh alot areound her and if the girl you're trying to get jealous treat her like a friend but ignore her, but not too harsh!
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.
Then he is a real idiot.
If he "loved" you more he would break up with his girlfriend to be with you.
If he really loved you he would dump his girlfriend for you.
If the boy has a girlfriend, find a guy that doesn't have a girlfriend.
You can either ask his friends and if you don't know his friends then be friendly to this guy and simply ask if he's dating anyone. It's called 'communication.'
You can try telling his/her parents.
yes. find another guy because it seems like your old one wasn't that into you.
uu wait till one of them dumps the other then uu ask the guy out : )
