If it was me I could probably not be talked around. Not because I am stubborn etc, but because it takes a lot to upset me in the first place, so a trial reconciliation would be futile. No talking about from practicalities with kids.
I would say that it was time for me to go, that I was sorry. I may have pre packed, to lessen the blow. I have been married to Mr Sense for twenty odd years, I try not to bottle things up, so I would expect that the 'vibe' would not have passed him by.
