The fact is, it is impossible to make a person love you. If love were something so fickle that just anyone could bend it to their will, it would not be worth a thing.
Assuming that she truly does love her boyfriend, you need to resign yourself to the fact that this is not for you to have; however, even if you believe that this is a casual relationship that will not last, do not pursue her in any way as long as she and her boyfriend are officially "an item."
Should the relationship end, do not make a move right away. Girls are very emotional and become both deeply involved and deeply attached in matters of love. Flirting is not a good idea in any situation when you desire to win a girl's heart, but it can be especially damaging during the period after a breakup.
The only thing to do is to make sure that this knows that you are there for her (which should be a piece of cake if you do love her, as you claim). The best way to stand out to a is to be a faithful friend. This will almost always get a young woman's attention because it is so atypical of most males. Treat her like the queen that she is to you, and she might just grow to realize that she cares for you in the same way that you do for her.
Well, to be honest, in my opinion there this girl I really love she has a boyfriend and I have tried my hardest to support her in the ups and downs. But now, I just give up because I'm purely heart broken I will soon probably resort to killing myself from the pain I'm going through.
Then she has to choose you or her boyfriend.
Does the girl know you like her? How long have you an and your boyfriend been together? And are you asking what should you do?
If he is her boyfriend, hopefully, she would like him.
Try an show her how cool you are compared to her boyfriend
Treat her better than her boyfriend does.
Wait till she doesn't have a boyfriend or move on
You get beat up
It means that they like you more then they like there boyfriend
Find a way to impress her.
fight the other kid and take the girl
you make a girl jealous and the girl will hate her boyfriend and follow you as her boyfriend and listen to that song Justin bieber one time
Move on, she's taken.
