I still think you’re holding onto her so tightly because you hate your current situation.

So what if you met up and she said she wanted you back? You keep saying that you can’t get out of the current situation you’re in because you feel too guilty and your girlfriend keeps crying… wouldn’t adding another woman to the picture just complicate things more? Plus be waaaayyyy more painful for your girlfriend if you actually left her for your ex?  You can’t start over with your ex while you already have a girlfriend. Bringing your ex into that situation would likely end up breaking you two up permanently (because who wants to go through that??) while devastating your girlfriend at the same time.

I think you should just do whatever you can to move on. Think of it as a wonderful learning experience but one that ran it’s course. Give yourself closure. And trust me, I know it’s not easy, but at some point you just have to concede that if our exes really wanted to be with us, they’d be back by now.
