I cannot accept that this is it.

I think when a WAS say they don't want to talk about it they mean they don't care about anything that you have to say, but want to give you a piece of their mind. Just validate. No disagreements, no debating. There may be time for that much later. For now, communicate with your ACTIONS ONLY.

Good job not blowing it up. That must have been a terrifying conversation. By keeping it level you set the tone for an amicable separation. That's a critical first step towards anything good!
