Not yet. I'm not there yet, but I think it's coming.
I haven't done anything about the phone/internet, because I was trying to show that I trusted her enough to let her have them. Clearly, she doesn't see it that way.
I haven't said anything to her, but I think my line in the sand is her moving out of our bedroom. If/when that day comes, I will pull the plug on the cell and internet, and expose to OMW1 (OM2/3 are not married...).
Hopefully, we don't get to that point. It's not normally my nature to be a harda$$, but I may not have any other choice.
From reading a lot of the other threads, once things go nuclear, they don't really get better; you just learn to deal with it, keep hope alive as long as possible and get on with living the best life you can.
