If a SAHM removes herself from the marital home, I do not support the idea of the LBH financing her lifestyle. Why should he pay for her to live apart from him while she enjoys not having the responsibility of working to provide for herself?

So, you confronted her about the PA. Did she say it would stop or that she did not want a divorce? Did she say anything, other than blaming you?

How old are your children?

Can you give us more marital history? Have either of you engaged in inappropriate behavior in the past?

It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
