If not tell her it's time for to find a new place to live, preferably sooner than later.
You see the problem isn't with finding things to say, its with having the balls to stand up to your wife, thats your problem and it's also your choice.
BINGO.. Somebody finally got it....
All the other stuff is kid's stuff in comparison. All she will do is find another way. When a woman LIKES a man in the right way not having internet isn't going to stop her. She WILL just find another way and then you will need another boundary. (Iwhich we are already discussing.)(like the car and like her talking on her phone to the OM in front of you and etc etc) and then another and then another..... until SHE tells you she is going to leave. How sad when you can be the one to set the pace here.
