<human>: Hello all. This is my first reddit postM. Some of my friends recommended me here to see what kind of feedback I'd get.

So I basically broke up with her around 8 months ago after going through 1 year together. It was the worst decision I ever made. I kept trying to go back to her and pleading to get back together. She didn't relent.

After almost feeling sure that she would never want to get back together with me, I start to try and move on and become really great and close friends with another girl.

Supposedly my ex found out about this girl and came to me to ask me back out, knowing I was in a weak position. I left the other girl, abandoning pour friendship and burning all bridges with her.

We have been together for about 5 months now, and I just figure out the reason why she wanted to get back together with me was so that I didn't get together with the other girl. I've gone to friends and they have told me she has always been manipulative. I feel hurt hearing that she would do something like this.

What do I do?
