Hi Bo106, welcome to the forum
I am so sorry to hear your wife is putting you through all this. If she would be fair she would just leave the house and that's it. Not that you would feel better then but at least a clear cut won't have you face her escapades.
What can I say? I don't think there is anything I can say. Nothing will help in this case other than her moving out. THEN time can start healing the wound.
