Yeah. That sucks, man.
I've been in the same shoes. In those situations, you know who your real friends are.

I think it's okay if a couple of friends want to confide in each other about a problem with another person.. if they want input or to express it. I think it's different if those two or one of friends have malicious or spiteful intentions in talking about someone who is supposed to be their friend. It's wrong to me to make friends take sides, even if I'm in the right. That's just drama.
I've been disappointed and hurt because a person I thought was a friend could not be honest with me.. but because of insecurity, she thinks she can vent her anger on me in indirect ways. That is very inappropriate and I won't let it seep into my life.
I am NOT a scrapegoat for others' problems, period. I hate drama and bullshit, but I love it if people are real to themselves with others. Acting on jealousy just creates more strife internally and externally, not solve the real thing. This has happened to me a few times, and each time.. these people just lose out. AND I lose out on real caramaraderie and getting to know them.
I find that a tragedy, because the whole thing could have been avoided if they were open with me in communications... at least we could have worked things out and had a real thing instead of something I can't bear to be around because of the toxicity towards myself. I won't accept it. I don't deserve it. Neither do you either, Felix. No one is worth that kind of time. Okay, so you know this person did a bad thing to you.. but in my experience, you can do nothing more than moving on and spending time on things you find positive and worthy of your energies. You just file it away in your mind that this person is not worth your time and trust because of her lack of integrity. Maybe she will change down the road, and be worthy of another chance.. who knows? Just be yourself.
I really, really respect people who don't act on their jealousy, b/c they are very courageous!! It is not called courage if there was no fear.
Just IMO

You decide for yourself what is best in situations like this, and I thought I would share my experience and thoughts.
