Indy, you got to let the guilt go. You are not looking at your own situation clearly.
You were a horny guy who tried to have sex with your plastered wife.
What puppy said! back a page. if you were truly the chester the molester you are making yourself out to be your wife would not be sleeping in the same bed as you and you would not have had stoned out sex.
her waywardness and your weakness are the issues, now. work on yours then start dealing with hers.
