Don't be a jerk or try to sabotage they're relationship, just be nice. Trust me girls like that, and if they break up be supportive and kind to her. When she's ready she might think that you could be a great guy. If she chooses someone else just keep being nice but maybe go for another girl.
Tell you her your feelings about her
you already answer that to your self
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.
It means she doesn't want to be your girlfriend.
There Will Be A Big Fight If You Love Him Then Fight For Him If He Has Another GirlFriend He Gonna Pay To you
if the girlfriend really love her boyfriend, she promise that she will never leave her boyfriend.. she will let go her boyfriend if the boyfriend doesn't want her already( ask for a breakup).. because she want to look at her boyfriend happiness even she is hurt and unhappy with her life..
No. Adultery is only relevant when one of the people involved is already married; being boyfriend-girlfriend or de facto is not considered enough.
Boyfriend and girlfriend
A girlfriend can trust her boyfriend by asking him if she can or be testing to see if she can. A girlfriend can set up some simple experiments by saying things that she already knows is true and then testing to see if her boyfriend is honest with her. Also, trust takes time and if the girlfriend has lost her trust in her boyfriend then he's got to get it back. Or he will be costing their relationship, big time.
Give up. She has moved on. It is time for you to do so as well.
If he has a girlfriend, don't go back. He will do the exact same thing to you, that he will have to do to his current girlfriend. Good Luck!
Try flirting with him/her, but not in front of their girlfriend/boyfriend. But then again, be friendly, you may want to be FRIENDS with them first.
