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.
-This advice may seem long but trust me, its not and it really helps!!!-
It is possible to get a girl who already has a boyfriend to like you. Trust me, I'm a girl. First, just start by being her friend. Be nice to her, and help her with any problems. When you get close enough, ask her about her boyfriend. If she says anything she's having trouble with, help her. If she talks about things she resents in him, be the opposite. If she says he never answers his phone, always answer your phone. If she says he needs to make time for her, make time for her when her boyfriend doesn't. Eventrully their relationship will get old, and it will cool down. Tell her if she's unhappy in her relationship, she should end it. If she does, great, if not, its ok. She might be having feelings toward you but doesnt want to tell you at this point so use it to your advantage. Now ask out a girl that is rather pretty and start to date her. This might make her jealous and push her toward dumping her boyfriend. Later on dump the girl you were dating and tell the girl you are trying to get that she wasn't who you thought she was. Ask for some advice or maybe a hug (girls like some sensitivity!). If you dont feel weird about it, try to get her boyfriend to make her upset. Tell him that she told you he was being weird, so he might get a little angry. Then she has a reason to dump him. Spend more time with her, invite her over, and watch some movies you know she might like. Talk about her boyfriend and convince her they are not right for each other. Soon they might break up (yes!).Keep spending time with her and then invite her over again. Tell her that you really like her and ask her out. if she says yes, great, if she says no, say it was a dare (dont say that too often though cuz girls dont like the whole dare thing) I hope my advice helps :)
Edit: While I respect the above answer - my point is this... WHY can't you find someone for yourself instead of messing up another persons relationship ! How would YOU feel if someone did that to you !
You don't. If someone is taken: don't flirt with them, don't gain feelings for them, don't make them gain feelings for you, don't make them confused about who they want, & don't be a homewrecker.
Secondly, if a man is willing to leave his relationship for you, what makes you so sure he won't do you the same way? If he'll leave his girlfriend so easily, he'll leave you just as easy.
You shouldn't be trying to go out with a girl that already has a boyfriend. You have to respect the fact that she is with another guy and respect him and her. You can be her friend and that's it. If she knows that you like her and she likes you back she should know what to do, if she wants to be with you or her boyfriend.
wait until they break up and then get to know her
Dont ever try to break two people up...the girl will end up hating you and you'll never be with her. i know that by person experience. Wait until or ''if'' they break up. than step in and help her get over it and make her happy
You just talk to her as a friend. Don't talk to her with the intention of stealing her away from her boyfriend. Just be friends with her as you would be friends with anyone. You're learning how to have relationships, and how to interact with others who have relationships. Having a boyfriend or girlfriend does not mean that a person has to be shut off from the world of other people.
It's not that you should have a flippant or disrespectful attitude toward one's dating status, but after all dating during the teen years isn't exactly the same as committed long-term or married relationships. It's obvious enough that even those go wrong sometimes. Boyfriends and girlfriends change; that also is part of what you are learning. But if you are aggressive, or out to 'hit on' or steal someone's girlfriend, you will also learn the hard way how aggressive a former boyfriend can be.
So just be friendly and treat people as you would want to be treated.
tell her you can treat her better then he can. over do him. impress impress impress.
You don't ! You leave him alone to get on with his current relationship - and find yourself someone who is unattached !
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.
