I have followed this thread from my cave. What a sucky situation. I would go with B.... if she "cares" she will contact you again (from one who suffers from major separation anxiety myself ...)

Sucks feeling that you were close to someone and discovering that they appeared to feel otherwise.... maybe it isn't uncommon for someone who is "deeper in the hole" than you..... they maybe felt "close" when they were more depressed and now no longer need you. Kind of familiar to me also. Good luck with this

I would be angry too I think I know you well enough to know you are not a grudge holder so that isn't as much an issue for you as it would be for some (I hope my "friend judgement" isn't off here..... again ..)

a growly,
Fuzzy
