No I don't know your wife. I do experience psychosis. But I hear what you are saying. I don't know what is best here because well, as Leed suggests to tell her in the presence of her therapist, I think that would be quite humiliating, being told you are being divorced infront of others, even your therapist.

I'm really sorry that you feel so guilty. I do understand, we all have our limits in our relationships. Have you talked to your counsellor about how to break it off?
