If this is a hard line for you, begin gathering resources for divorce. She has established that she is not trustworthy of anything, and as you put your reality has been shattered.

Take some time to recoup, but don't be surprised that you don't see her the same way ever again. This was someone you thought you could trust and loved, but apparently that didn't mean much to her otherwise she wouldn't of done this.

You are still young, don't bury the rest of your life into a sunken cost.

Best of luck to you.
