act mysterious and give her a sign
Treat her better than her boyfriend does.
wait until she breaks up with her boyfriend and then make your move
give it a shot
Patience. You shouldn't expect her to like you as a boyfriend if she already has one but you can still be a non boyfriend.
try to impress the girl if that doesn't work sorry shes gone
If u like a girl who already has a boyfriend but you dont know if she likes you or know,the first thing you have to do is that you will have to make friendship with that girl and if she is already your friend,then increase your friendship and one day confidently ask her that what does she feel about you..
It means you may like him too, but you should stay committed to your boyfriend of 3 years.
Maybe she just doesnt want to go out with you.
Now prepare for the boyfriend to come after you, and wait to see if the girl seems to want to spend some time with you.
get her while shes in a dark alley and give her a snog whilst your upside down and in a spiderman suit she will think its totally romantic and ditch the other guy
3 possible reasons: The guy could like the girl, and wants her. The guy may not know that he is making things awkward. The guy could be intentionally make things awkward because he dislikes the girl, or her boyfriend.
If the girl has a boyfriend already,try not to get in the way. If she really does love you then she will break it off with her boyfriend. Don't try to rush her though as girls don't like that. Trust me, I am one.
