She was probably trying to get back at you because she took what happened the wrong way. When you left and didn't say anything to her she probably received that as you going off with another girl. Of course she was wrong but it's what happened man. It's going to be hard but move on. Clear your mind as best as you can. I wish you luck.

From a girls perspective that's down right like a hoe. Good chicks who want to stay committed don't do that. I'd fine someone else.

Move on man, horrible thing for her to do. Not even worth your time anymore.

She clearly doesn't care if she was willing to have sex with another guy because you had personal problems going on.

Avoid that shit like the plague, she's a toxic girl. Don't smash before your dip, chances are you'll catch feelings again and start talking and end up forgiving her.

Dump the girl and make a statement to your parents by moving out.

Things will change and your live will get better, dont lose heart

She's really not worth any more trouble man. She clearly didn't like you as much as you thought if she decided to have sex with another guy while talking to you. Now if you did that, she would never give you another chance & might even call you a f*ckboy. Move on man, don't bother wasting another second on her. I'm sure you're a great guy but you don't deserve to be hurt.

Move on.

Agreed. Just move on man.

It will be hard at first, but overtime it will get better. There is definitely someone better in the world than her. I promise you that.

Just be friends for the time being if she really really sorry for what she did she'll do everything in her power to get you back
