You've already told her point blank that you don't want the divorce and are willing to sit down and talk about this when she wants to.
I am not sure what's the point in reiterating the same thing to her. Good thing is you don't have to respond tonight.
Wait for one of the vets to weigh in.
If I had to text anything to her it would be - "I have already said that a divorce is not the solution to our problems, but I won't stand in your way if that is what you want. I am willing to sit down and discuss this with you."
DON'T SEND SOMETHING LIKE THAT YET!
Wait for some more comments. Most importantly, don't panic and never respond when you're emotional. When in doubt about what to do, do nothing.
