Ellie (aka kml) makes very valid points on the other side of the equation: divorce from GUBU's perspective. I agree to a point.
I just don't think that you have to bend backwards just to be cooperative if a divorce isn't what you want and GUBU seems to be lukewarm to the idea (his actions has shown this thus far). Let him do the paperwork and present you with a plan/offer. Then sic your lawyer on him with your needs and wishes as it will become a business negotiation.
If...a big IF....GUBU repeats his request for a divorce and wants to proceed ahead with it, then I you can say "I am sorry to hear this. You know this isn't what I want, but will not stand in your way or do your legwork. You will need to work with my lawyer on this."
Or it could be other reasons for 'the talk'.
1) Concern about your health as you've had some rapid weight loss
2) Discussion about taking care of the animals that have been a drain on your time and energy
