I've been marathon reading self help books and posts on this site including your sitch. I see a lot of similarities in our sitches. It's difficult to give weight to anything the W says when they are in crisis mode, but when she makes comments about whether I was happy, or says "I'll find someone new" it makes me think that she's confused and dealing with something internally. I've suspected perimenopause as possibly a factor in triggering the second cycle of my W's MLC. Do you suspect this to be a factor in your sitch?
