Same as you, yesterday it was D definitely. Today I'm not so sure. I think I'm expecting him to ask it's been 2 years of separation so in the UK we could get D (I think not sure of the legalities).
Probably best to wait for him to bring it up,if we ever speak again, and then wholeheartedly agree. He will one day lose his temper with me and threaten of that I'm sure - when that happens rather than ignore or smooth it over I'm going to say yes, please sort out the paperwork.
