Note : you going to someone ELSE's home who can help protect you from his affair will make going dark a LOT easier... why do this on your own when you don't have to?
A LOT of spouses try to do this on their own... its a LOT easier and more comforting to setup a safety zone from the affair and have your friend take your place why you support them maintaining their home... everyone wins except the affair partners...
I can't stress enough the value and impact you have on him when you are GONE from that house and have cut him OUT... it will plague him like you would not believe.. and he will have no choice but to take his panic out on the OW.. why would you NOT want to bring that to her door?
It's a solid punch in the gut to her... One shes due for in my opinion...
