JJ I do agree with you and also will add that porn is here to stay...unfortunately!

Katebbca as difficult as it is to remain completely impartial when it concerns your parents and their marital problems, you should try. Be honest with them both and tell them that it hurts you deep in your heart and soul to hear them belittle one another, that you refuse to take sides. Tell them if they insist on trying to include you into their marital problems you won't visit any more...As far as your dad and the porn goes it sounds like thats all he has right now especially being an invalid unable to pursue outside activities. I have no answers for you regarding that, I wish I did. Personally I would steer clear of that as well. It's between him and his conscience....
