You are letting her use you, dumbass. Whenever your girlfriend starts to waver don't interfere. If she likes someone else, there is little you can do to make her like you, and even if you get her back she will likely do it again. Tell her to make a choice, and leave it up to her to stay or to go. If she stays good, if she goes then NEVER, EVER talk to her again at least for the next few months or even next few years. After a while though it may be nice just to talk to her again and catch up on her life, remember the memories and the such. However, never dwell in the past. You made a big mistake telling her that you still love her. It just encourages her to do shit like this and it makes you weaker.

TL;DR Well I skimmed through it. You're 18, young, still got a whole life ahead of you blah blah, there's plenty of fish in the ocean, not just your ex. If your relationship requires that much drama, speaking bluntly, it's not gonna work. It's gonna consume your energy, time, and happiness if you keep it like that. Move on. You're thinking too much, asking yourself too many questions, you think she's playing with you, it feels like a game to you- it shouldn't be like that alright? As for any breakup, you'll eventually get over it. Yes love is a drug but this is the wrong kind of drug. Years later you'll look back and you'll shake your head thinking how young and naïve you were. It's not the end of the world. Go out and enjoy life.

Ain't you never heard of paragraphs? daggum' kiddies and their poor story tellin' skills 'n whatnot.

Youre a dumbass. I made damn sure I made no contact with my ex when she cheated on me.

I would go see her and talk to her. There's obviously a lot on her plate and she sounds confused. Don't jump into anything though. It looks like she's is using you as a sense of security and any girl who would leave you for a guy like that... Just be careful bro. You deserve better.

Your a total beta bitch if you take that hoe back. Ignore her and move on. Tale her back and she's just gonna keep walking over you because you put up with it.
