If she's a shitty girlfriend then use her for sex! God I thought that was obvious.

Have sex with her, then dump her.

She's young and emotional, and doesn't know what she wants.  Just like you.  I doubt she's "playing you" intentionally as some have suggested.  She's just living the emotional rollercoaster of every 16-year-old.

Don't worry about it too much.  I went through the same thing when I was 16.  You'll look back on this and realize how silly it was.  If you think it's worth it, give it another shot.  The worst that could happen is that you break up again, and you have to find someone else, which you'd have to do anyway.

She's lying to you and being sloppy about it and doesn't really care about you and only cares about herself. She didn't MEAN to lie and hurt you, but... it just "kinda happened." She thought she wanted to get over her true love, then... got distracted and was single so she got with some other guy, and that didn't work, and then she remembered she liked you. She's got some growing up to do before she can settle down emotionally.

Don't worry about your feelings for her. It hurts and it sucks. You'll have to get over this. You will.

But what you need to do is look at this as an opportunity to break that bitch's heart into a million pieces and force her to grow up faster.

She says she wants to get back together. Say yes. Then take her out on a date, really far away, get her naked, and drive off with her clothes!

Good luck!

From what you've said about her it seems like she doesn't care about you and only sees you as a backup. I personally could never go out with anyone like that and would rather be single and have my self respect than allow myself to be used like that.  I realize how hard it can be to deal with the kind of feelings you're having but hopefully you can get over her because she has shown that she can't be trusted in a relationship.

she is a liar and was playing with you, gotta confront her about the lying before that she went out with a other dude short after and wasn't her "true" love if you really want to be with her.

Without much hassle I hope you don't REALLY want to be with her that bad and forget that girl (I wanna call her worse just cause of lying)

 STD(s) and some other guy(s) she is stringing along beats the hell out of him in a jealous rage? 

Though I would guess she is simply using you when you're convenient for her, it is possible her intent isn't malicious. What is obvious is that she's very immature and not suitable for any relationship.

You guys are young and shouldn't be getting wrapped up in all this. Trust me, unless you're lucky, you'll have your whole adult life to go through this kind of misery. Enjoy being young, meet different girls, spend time with your family and friends, and plan for your education/career. Time is short, make the most of it.

Dr. Phil's all over vgc.

Then have sex with her best friend. In her bed. While she's in it.

well i know for a fact if u go back out with her she will do it again and again so forget about her!!!! find a new girl that'll stay with u!!!!!!!!!!!
