What grabbed me in your post is that you said he was 90% sure he wanted to leave.
Well, my wife told me the same thing, more than once. Even 2 weeks ago, when things began to turn around for her, she said "you know - I was 90% out the door, and that door was closing, not opening".
My wife now wants to reconcile, and we are back on the road to starting a brand new marriage.
So - my point. 10% is not zero. I am living proof.
If you envision a negative outcome, that is what you will project, and possibly get. So, change your thread title!
