HB - he is cake eating...isn't he. When you say to shut him out. Do you mean go dark? How can I do that when we run business together and have to work as partners....
Yes, he's CakeEating, cycling, and it must cease, or he stands to lose you totally. This cannot continue.
Remember, mine never left home nor moved out during his crisis. When he was trying to get rid of OW, after confronting him, and got a handle on my feelings, I totally distanced myself from him until I KNEW she was gone, it wasn't easy for me BUT.....it CAN be done. You can deal with him in a totally detached way in the order of business, but your attitude needs to be VERY distant with him. Emotionally, you will need to shut him out, AFTER confronting him. Not easy, but it CAN BE DONE.
He has to know this is NOT acceptable to you, will NOT be acceptable to you, and he has made a very serious mistake by not only giving in to the OW again, but LYING to you by omission, comission, and the list goes on.
After confronting him, gather your strength to distance yourself totally from him; effectively putting the ball in his court.
Mila, you're NOT an idiot, at least you were paying attention to your intuition.
The signals are not always clear, but you KNEW/KNOW your husband better than anyone, and I did say on the alt that if something was up, you would KNOW.
As hard as it is, you will have to put your own feelings aside after the confrontation in order to deal with him on the business end of it.
I'm really sorry, Mila.
Remember, as each person is different, every MLC/Transition is different..what works for one may not work for another. Most of the time it is trial and error for ALL involved.
