Disappointed in Membership

[disillusioned]

I'm posting this (relatively) anonymously because I don't want there to be any repercussions for me, or for my friend who's a member of the same greek letter organization.

A while back, my best friend asked me whether it was possible to rescind/renounce your membership in one greek letter organization in order to become a member of another. Ironically, it's this friend who convinced me to become a member of our sorority, but now she's really disappointed with the pervasive attitude she's seen from the women in our chapter.

While I've done all I can to try to get her to hold her head high, and to hold on for better times, she's convinced that if she moves to a different part of the country and doesn't make any mention of her prior membership, that she can become a member of a different organization, an organization that she now claims was her first choice.

Since I don't know of anything I can do to get her to change her mind, I guess what I'm really asking is such a thing possible? Can a person join another organization? We're in an NPHC organization, which usually signifies bonds for life.

Thanks for any honest responses. Any ideas on how I can get her back into the fold are greatly appreciated as well.
