you can flirt and show off the goods, but remember if this boy chooses to be with you another girl could come along and do the same thing. Then you will be left hurt like his current g/f
make him like you better
If the boy has a girlfriend, find a guy that doesn't have a girlfriend.
Make him think that you don't know and show him that you like him allot so later he could brake up with his girlfriend
be jealous and then try to be friends with that boy until you get close and then you can make her jealous.
Someone has to ask the other to be their boyfriend or girlfriend in which then you will be a couple.
do him, and he'll like you (possibly more than his girlfriend).
If a boy has a girlfriend then he is considered taking and you should leave him alone and later he may break up with his girlfriend.
Only if you want to be his girlfriend. it does if u say yes
forget about that boy!!!!!!!!!!!!!!!!!!!! Answer dont mess with him
Hit her in the face.
If this boy has a girlfriend, you need to respect that he chose her. You can continue to be a good friend to him, but you can save the schemes to make him mad for you until he is single again.
It is okay for you to like her, but don't make any moves as this could end with your friend being mad at you, and his girlfriend being even more so!
