What to do when your wife is insane?

The signs were there, and you ignored them. You love(d) her, and were probably hoping certain things weren't true or would change. You can't change the past, you can only decide what to do with your future. We all make mistakes, get "blinded" by love, it happens. Time to move on. I'm glad to hear you are in the process of doing so and wish you the best of luck.
