What a turn of events the last few days! I think you are wise to anticipate a possible temporary pulling back from your xH...maybe he won't but always good to be prepared!
The follow up email was very nice and shows he really did need you there and appreciate that you were there!
As for BMF...I don't know...sometimes besties think that they are "above" or excluded from requests...maybe he thought that even tho xH wanted to be alone that that meant alone from everyone but him...would xH be the type to let him stay even if he didn't want him there?
I like sanderika's idea of filling the fridge!!!!
