UPDATE - Rabbi has been converted to my side (pun intended)

I got two responses. The first was a bit snarky and I sent a barbed email in response. Not my finest moment, to be sure. I know better than to send an email when I'm angry, but I did it anyway.

To my shock, I received an email that included the following:

"Firstly, you are TOTALLY justified in wanting a break from all the pain of your relationship with H. Scripture is plain that you are a temple of G-d's Spirit, and the protection and care of the temple is a great priority.

(he quoted some scripture)

In fact, H has not at all been treating you as a temple, but really defiling and destroying you in many severe ways. He is indeed "of this world" and in violation of Torah and G-d's will, and hazardous to your health and well being. You are indeed in a toxic marriage, and this action of separation would have been justified many years ago. G-d bless you for your current action in appropriately honoring yourself by requiring a separation.

Secondly, I am really impressed that you have maintained your faith in Yeshua and scripture, despite the fact that the one who led you to Him has been a dramatically a misrepresentative of holy manhood. It would be easy to "throw out the baby with the bathwater" and abandon your faith in light of this horrific example of Messianic/Christian living. I am really proud of your discernment and depth of faith and understanding."

He added one more line that shows he's not a fan of divorce...

"This is all to say that separation and boundaries are right and good and needed. But, that is still not the same as abandoning hope for the relationship altogether. BUT, only after massive intervention and real repentance on H's part!!" ... but is also practical enough to see that it might be warranted.

All in all, I'm extremely impressed by him and have told him so.
