you don't. why do you even want to break a couple up? pathetic.
wait until she breaks up with her boyfriend and then make your move
Make a move to be her boyfriend trust me im a girl i would know.
If you like a girl hug for a wile and then make your move.
She may not want a boyfriend. She may not be trying to attract a boyfriend. Or she may not be the most popular girl, and the not popular boys are too scared to make a move
Wait till she doesn't have a boyfriend or move on
Sure why not i asked out my boyfriend and i held his hand first
You don't. She has a boyfriend. Move on.
If the girl in question likes you then you won't need to convince her to let you be her boyfriend, you must wait for the signs to see if you think she is interested, let the girl make the move, don't be pushy, be patient.
yes
Move on, she's taken.
She's taken, move on.
Ask him : How about to make a move right now ?
