yeah thats tough.. she was another part of your life and although she obviously still cares for you.. her obedience to the WTS does not allow her to acknowledge that in her actions.
My ex best friend (that is what I call her), last December when she had word I was home (for Xmas no less), called my son to get the scoop on me (he was never baptised). She couldn't of course seek out me.. its ok.. I know she still cares.. as does your friend..
the difference is, now we build friendships that do not require us to be WTS followers.. its not a conditional friendship
