Stop having R conversations with her. You are right, they aren't helping, and her words are cheap at this point.

Don't act on emotion. It's okay to be pissed at her right now, but don't show her that nor should you make a decision while emotional.

If you are ready draw a boundary about not sharing a house with a person who is having an affair, that is the assertive thing to do. But don't get drawn into a conversation about it. Again, her words are cheap.

Hang in there.
