I'm confused, what's going on? Who's leaving?
From just what I read here and what I glean from her comments, Seha seemed dissatisfied with her life situation and even her own sense of self-worth and identity.
I am just guessing that from her recent posts about searching for someone she had become a bit infatuated with, that she is also trying to expand her life situation and sense of sexual identity. I had gotten the feeling that would be hard on Proth, but his post indicating his absolute support of her decisions (which would ultimately lead her away from him) seemed very sincere--stepping back to be someone's friend first, when you have feelings for them, is very hard.
Why she would choose to leave behind FFXIAH.com--perhaps what she saw as a vestige of a childish part of her life maybe--is a bit confusing, but as people said, a lot of people come back. (And some, who were even banned and forcibly removed, I think, never even left.) ^_-
Hopefully she finds peace in herself. I personally hope that she doesn't fall into the trap of thinking of sexuality as some kind of exclusive polar attraction (all-or-nothing, het or gay) which sadly removes a lot of potential happiness from life, and missed chances (I feel at least.)
