Tim, sorry to hear this - but you probably shouldn't be surprised.
For years my W would never friend me - I guess that should have been some sort of clue? I think the garbageman is a friend, as was some guy she met in line at the market. She used to have something about loving husband, la-de-da on her page, but that went down sometime around her ILYB... I've never been a FB person - but she's addicted to it.
Not sure what her FB says now - since I really can't access much about her page anyway. And, I don't care.
Anyway, keep plugging along and don't put much credence into a FB page. It's just as easy for her to change it back if that time ever comes. She could have just been having a bad night.
