I told my husband that as long as he was choosing OW he could not live in the house. He couldn't have it both ways. I presented it as a self-respect thing. I ended up filing a petition to be the sole resident. Once he left I changed the locks. He didn't put up much of an argument because he knew he was in the wrong
There may not be any way to avoid a scene but you have to set appropriate boundaries for you.
