Seems I’ve got the alternative opinion here. Take it with a grain of salt, but I’m going to be a bit harsh.

“I want it to work.. But I’m scared and turned off at the same time, I feel like what we had was ruined because she chose to touch other people..”

Let her go, dude. She deserves better than you.

And you deserve better than the tangled mess that will result from getting back with this girl. Go back to working on yourself. Because you have a whole lot more work to do, and you can’t do it with her. If you get back with her she’ll only reinforce your unhelpful attitudes and you’ll fall into the same patterns that made you unhappy in the first place. It’s very hard to have a genuinely new relationship with someone you’ve already been in a relationship with. And it doesn’t sound like either of you are up to the challenge.

Why is she crying about sleeping with these other guys? You dumped her! Or she dumped you, it’s not clear, but either way, she was free to sleep with as many guys as she damn well pleased. Why the hell are either of you sadfaced about this?

I can’t escape the impression that it’s because somebody else touched your toys. Because some twisted part of you thinks you owned her, even after you dumped her, and nobody else gets to touch her, and she’s not allowed to make her own decisions about that. Hey, it’s hard to find such ugly thoughts inside yourself, and I understand you’re confused by it. But it sure looks like that’s what’s going on here. You weren’t betrayed. Your idea of her being your special posession and yours alone was betrayed. The idea that you could put her down and pick her back up whenever you liked. And that idea was fucked up to start with.

She did nothing wrong. Your jealousy and your sense that she’s gone and ruined it by touching other people is irrational and unhelpful. You need to work on that jealousy, and on your attitude, and you can’t do it while you’re with her because she seems to suffer the same blind spots. Let her go, wish her well, keep working on you.
