Seriously, hold out for sex. No sex, no more emotional coddling.
A lot of women who are emotionally unavailable will use the old "friend" routine. There is no risk for them. So they use the sublimated sexual tension to get a lot of the emotional nurturing that a standard relationship is supposed to provide from a male that is either dysfunctional enough, inexperienced enough, or has low enough self esteem to fall prey.
Its a tired and boring pattern of human beahvior . . . but oh so predictable. I will say one thing. Nothing is more tedious and boring than meeting people like that. And I despise people that are boring in self destructive ways. *Yawn*
