Just journaling. Don't care about the who, the why, etc. Just a signpost.
MLCer is still stalking my fake OLD, but since the drive-by has not contacted the at-home child (or presumably the back-at-school child). Neither shows any sign of caring and indeed have not mentioned him, but this is the longest period of NC with them since he first left.
I've decided to deal with the potential question of marital status by saying we live separately. Just can't bring myself to use a legal term of art like "separated" that could have profound financial consequences in any setting.
