I voted no because it will be a cold day in hell before I leave my home for something I didn't do. I've been married a long time. I've EARNED my place.
Mr. Nasty can leave and forget he ever lived here. For real. Oh and he can also leave everything he bought too because that would belong to me now. 
The disrespect is what would bother me most I think. If my husband looked at porn while I was away from the house or when I was asleep, oh well, but not in my face. And not with our money. Because it is OUR money. I would never disrespect my husband in that way and I expect the same in return.
Men are such deviant creatures sometimes. The bad ones we women can do without.
I know your lady friend is hurting, she already knew her answer before she told you the problem. I wish her luck, tell her to be brave, never settle for less. Life is too short.
P.S. Chocolate ice cream makes me happy but I don't constantly eat it.
This may not be a good sign for your friend. I hope they have no children.
Like drug addiction this guy may decide to " Kick it up a notch" and looking replaced with actual doing with or with out the consent of others.
This is not just having a subscription to Play Boy and keeping them in the bathroom stuff, or even having a girlfriend on the side, this, as described, is creepy stuff.
This friend must be becoming afraid of what is happening to her husband, what he is thinking and perhaps doing.
Were any of my friends to tell me about this problem, I would take it as a cry out for help.
A very ugly thought comes to mind at this point, in the last few years we have read about woman who go along with their husbands committing unthinkable sex crimes to their own children and kidnap victims. Why on earth would they do so, are they not just as guilty as their husband in all this ? Why have the men become imprisoned for their crimes and the woman who enabled these horrific crimes given sympathy and seldom judged.?
