I amazed once again at your strength. Yeah, you need to stay rooted in that house. I'm glad you've made that decision.
By the way, SO is not rational so having all the arguments covered may not even work. But regardless, just state your position and do not waver. I believe he will be comforted by your strength. Like a horse with an owner who shows whose boss. Also, inside he will probably be comforted and glad that you are making a stand, because I don't think this is really what he wants, rather what OW is pushing him to do. She really needs to get a life.
