Newbie-H away with OW

[Train]

I'm not sure what your question is.

He's going to continue his A as long as he wants to.

You stay in the house. You sleep in your room. You live your life. You have some fun. You act like he's not even there when he's there except to share a "hello" in passing, like you would a neighbor. ***If HE mentions your relationship**, you tell him that the current state of your relationship is not what you wanted but that you've finally realized what you deserve in life, and you're SURE you don't want to live in an open M, and neither WILL you live in one. And then you go on about your life. You don't meet his needs. You don't cook for him or clean for him or have sex with him or validate his feelings. You go out and have some fun. You stop worrying about how every step you take may make or break your relationship with him. You stay in your house. You sleep in your room. And you LIVE YOUR LIFE. And let him live his. And then, in time, watch him fall on his face.

If he wants to move out? He can. He's a big boy. But meanwhile, go live your life and don't meet ANY of his needs. Let OW have that job for a while. And let's see how she stacks up.
