You dont......... Plain and simple.. Move on really, if he left you for someone else then you are better then him and he wasnt fully into the relationship.. You dont need to do anything to get back at someone.. Just know that you are the better person here and move on........
My dear friend, no one can "steal" a girlfriend if she doesn't want to be "stolen". And a friend does not "steal" his friend's girlfriend if he is a true friend. Maybe they each got what each deserves. Just wish them well and find a girlfriend who will stay true to you.
ANSWER:
If we all think of what we can do to revenge our pain because of a man, our life will never be better. It might feel you better if you get even to this woman because your boyfriend was stupid enough to chase her. Before you think on what you can do to this woman, why not ask yourself why your boyfriend betrayed you. If he didn't found her, do you think she will be the one that you will be angry to?
Let me give you a small pep talk, it's not worth it. Don't let yourself be as low as the woman and that man you call boyfriend. Try to move on, start with fresh out look of life, I did it and mine was worst than yours, and now I'm happy. I have a peace of mine, my children, my career, and my own world. If we all can do it, I think you can better than others.
You can find someone better out there, but God has a plan for you, whatever happens it is because God has the right guy planned for you!
Boyfriends are not property and therefore cannot be 'stolen'.
If your boyfriend wishes to be with someone else then that is his decision not yours.
Stop being their friend
steal his boyfriend and laugh at her
tell her that her boyfriend cheated on her. she needs to know.
If you want to but remember, you did the same to him.
beat him up.
Dude your a lesbian.
you might be getting cheated on ):
get rid of him he doesnt really care about you girl!
obviously that person is going to deny having a fling with your boyfriend
Let him have her, and find yourself someone who respects you.
* Hanging out with another girl * Avoiding you in almost every way * Not talking to you * You finding a note from your boyfriend has dated that girl
how do you know if your boyfriend has cheated
She probably feels bad after what she did to you. Even if you now hate her after what she did to you she feels the same way as he was her boyfriend too
Sounds like you need a better boyfriend.
