How do I get revenge on a girl "friend" who broke my heart?

Umm I think you should be mad at your best friend not her. Why is he going with her doesn't he know you like her? Girls are not mind readers or physic any more than guys are, so unless you said to her I like you she probably didn't read the signs that way or just thought you were a flirt. Usually if a guy is in the friend zone for most girls that's where they'll stay. Don't blame her for not making a move. Maybe you should just tell her how you feel. As much as it may seem like she flirted with you sometimes girls send out the wrong messages.

If I was a the girl in that position the best way to get back at me would be to continue talking to me while dating a girl that was as equally as hot as I am, and what you should do is get really close to her, show her what a gentlemen you are and then brag about how wonderful your girlfriend is give her every detail, tell her about all the nice things you do for her and the nice things your girlfriend does for you, but by all means never tell her about sex that you may have with your girlfriend or making out. You want to make her jealous as possible so be really kind and sweet to her. Let me tell ya! If it was me I would be so jealous that I'd prob cry and tell you to break up with her. Do things to your girlfriend that would give you a "gentleman with the ladys" reputation, she'll hate it and it would make her jealous and she'd be hurt at the same time.

I think you're being REALLY childish. She has no obligation to you as you weren't dating.

If you don't want to talk to her you just tell her that! USE YOUR WORDS, there is no need for games.

Sooooo. You are trying to hurt her feelings because she is going to prom?!?!?!
first of all. You ARE trying to be a jerk.
second, she isn't your girlfriend, so she can go to prom with whoever she wants, she has no obligation to you
third, I think you are being incredibly immature.

fourth, if you thought she liked you back, she was probably just flirting a little too much. Girls do it all the time, we flirt with our guy friends because its fun. And a lot of times we don't even realize we do it.

I'm on this site to give advice, so if you want to make her jealous, start being best friends with a really cute girl. But think about how immature and selfish you are being.

Wut I do when a boy brakes up with me is talk to a lot of boys and I make sure he sees that. I also make sure that im laughing when he is around so he doesn't think he broke my heart even though he really did. And I also try to get a boyfriend asap so he knows I've moved on. Hope this helped a little. Good luck with getting revenge

It could be that she honestly didn't know that you liked her. Or if she did know, that she just doesn't feel the same way. From what you say, I would guess that she didn't mean to hurt you by this, and probably had no idea that you felt this way about her. We can be kind of clueless about the feelings of our male friends sometimes. That doesn't mean that your friend deserves to get hurt. I think you're taking this too personally, and that the only way to sort things out is to sit down with your friend and tell her (politely! ) how you feel.

I honestly don't think that she did this to hurt you or to break your heart. And I think that she deserves for you to at least tell her the truth. Lying to her and continuing your current behavior is only going to confuse her. If you wanted to go to prom with her, you should have asked her first. I can hardly blame her for asking someone else when it's this close to prom and she didn't have a date yet.

You could make her pay in pain, but I could never could make you stay

Get over yourself? Negativity never helps anyone (even if it is kinda fun).

You are trying to be a jerk. Don't do anything. At the worst just avoid her, and don't do anything more. You are over reacting. She didn't try to hurt you; she has the right to do whatever she wants. Don't try to deliberately annoy her; that is very immature.

If you don't like her anymore then avoid her. But you probably lost a lot more than she did: a good friend. This is nothing to break a friendship over.

You are hurt because you didn't make a move. Don't blame her. If you have always liked her, you should have acted on it a while ago. You were too slow. Even if she did have feelings for you, they disappeared with your lack of action.
