Hi Goldfighter,
Im sorry about your situation. I must of missed alot. How long were you married for and do you too have kids? from what i read she is a lyer. You need to move on like a previous post said there are plenty of fish in the sea. I would cut all ties with her. dont respond to any texts she sends you. ignore any calls form her. do not contact her at all. hire a lawyer to do all the contacting for you to settle whatever you too need to settle.
Once her ex finds a new women he will drop her quickly. It will not last. remember im sure he is saying if she did this to her husband she will do this to me.
she will realize what she lost. remember Karma is a B. if you need to talk im always around.
keep your head held up high and keep positive. You will get through this one day at a time.
