I have been thinking along the same lines. She needs to hear exactly that.

What follows scares me. If I need to follow up with actions then the logistics of separating will be a nightmare.

I can certainly just leave evrything behind and move out, but I don't trust her with our pets. Even though she has gotten more responsible and sober lately, I don't trust her enough yet.

I know that it's not my problem but it would bother me all day and night thinking whether she has neglected the animals and went back to her drinking sprees.

Maybe I should add some of that to my statement. "You have shown very little regard towards our pets for last 5 months and until I am comfortable that you have the will to take care of them I will not discuss the logistics of the separation."

Honestly I don't know how that will ever work given her schedule and style.
