Regardless of what may happen in the future, there will always be a positive outcome for you, with or without your H.
I know it sounds mean to think this way, but I know that our S's will hit rock bottom once they realise exactly what they have done, and what they have lost. Of course this will happen when it is too late.
I am seeing it in my W now. But like you, I am not going to put myself out there for her anymore. She would have to really change and re-committ 100% before I ever let her hurt me again. I am still working on a great friendship with her, and will continue to build it for our DD's sake, and who knows what may eventuate.
I hope the next few days are good ones for you. AndyV
