He's been pulling out a charm offensive lately, I'm not sure what that's about. Not helping one mite more, not spending any more time with the kids, but making a show of being friendly and accommodating when he does turn up. Complained that I won't allow him to be nice to me (as in, I'm not sufficiently responsive to his friendliness). None of this means anything; he just wants to look like a good guy.
MB- I've gotten a fair amount of this as well - not really a charm offensive but repetitive offers of "I want to help!" - which are completely empty given where he lives and his schedule. I guess it makes him feel good to say it.
I hope you are one of those fabulous stories one reads about where the house sells for over listing price the first day on the market.
