He's making no sense. He considers the relationship over, was sad that he was never planning to stay in the house again after last weekend but also wants a key to the house? He's going to tell the kids you're separated? Does he think that him living elsewhere for the best part of a year has gone unnoticed by them?
I wouldn't meet up with him, Dilly. He doesn't want to be married, and he's too scared to get divorced. You're not going to get any sense of out of him - your own action is going to move you out of this situation, he isn't going to grant it to you because he can't.
