I was thinking of you and your situation this afternoon. It makes me really upset, cause sometimes you think like your relationship is ****ing good and then BANG : no it isn't . I would be extremely devastated if it happened to me, but the truth is , even if there are such heartless people ,the world is full of good and worth everything people .I hope she didn't destroy this optimism in you, cause you're a great guy and I'm sure you can find a great woman. This is life, it happens that we meet such extremely bad people ,but who knows, maybe you needed to meet her so you could meet the love of your life. Nobody knows . From my experience, I've learned that all the bad things that happen ,may look very bad at the moment that they happen, but in the end they bring something good, and when you look behind, you're glad that this thing happened to you cause the good thing wouldn't happen without it. And I don't think you need a talk with her to have a closure, you already have your closure, you know why your relationship ended and this is your closure. There's no need to engage in further conversations with her, let her feel devastated and mutilated by the very very bad things that she has done. Good luck bro.
