Hi supernaught, I'm really sorry the relationship turned out as it did and she clearly put you through a lot
But real kudos for managing to end it and sticking with staying away from the relationship/holding with your standards/what you know is right, it sounds like exactly the right thing to do although I'm sure it must hurt a lot.
Right now, you're probably grieving the person you knew at the beginning, the person she is without that side to her (although there's no getting away from the fact that that side is there) and the loss of the relationship. And it will take time to go through that process, to let go...........but just know that you've done the right thing by ending it.
Now you're probably going to feel a multitude of feelings.........sadness, emptiness, anger, betrayal, wanting her back, pain, frustration and some of those you may need to feel/go through in working through it all, but just as much you need to focus on you as well e.g. trying to do things for yourself.........things you could enjoy..........different activities...........spending time with friends or other people................
But some of those things she did to you...........they sound pretty bad...........you might need to talk to someone about them, do you think?? It sounds like you've been through a lot and those things might have a big/longer term effect on you, and hey you know "bottling things up" can just make them so much worse, right??
But in your own time if it might help, if you can manage it, alright?? There might be someone in your life you can gradually confide in, it might take a professional, or you can always talk to us you know.
