Afa, the consequence of leaving the home makes sense. You must be prepared for her to actually do this, though. Maybe she won't, but don't be surprised.
The D filing would be the next step, but be prepared to follow through too. I think that might've been one of my major mistakes. I told my H that I would end our marriage if his EA turned into a PA. He had the PA and I still gave him another chance. Then, I told him one more contact with the OW and I was out, so he continued contacting her and when I found out, I did call the lawyer, but stopped the process when he asked me to do so. Finally, I told him I would end things if he decided to date other women while separated. He said he had made the decision to date other women in April (even though he hasn't dated anyone,) and I haven't ended anything.
But I do know that if I find out he is dating someone, I'm filing immediately. I guess this has helped me find my real bottom line. Think about this for a while: what is your real bottom line? Then, communicate it and follow through with it.
