could it be that Faith is just an example of how slayers normally are?
What passes as normal post the activation spell is that, apparently, the girls do, in fact, have a choice in whether or not they want that life, and almost certainly have the right to take some time off if they need it. Front line soldiers aren't just allowed, they are required, to take down time, simply as a method of retaining their peak level of efficiency and, in some cases, their very sanity, and part of that down time is the opportunity to associate with non combatants and civilians in order to, as much as possible, forget, for a brief moment, what their job actually involves, and the possible, indeed almost certainly inevitable, end result of that job.
By any sane standards, she is long overdue for some form of leave and the opportunity to enjoy a real normal life, complete with friends, if only for a short time.
I have to take issue with this. Why is it 'insane' to not want or need a relationship at a certain point? Why is Faith 'long overdue'? What if she just doesn't feel like it at that moment? What if she feels that- as a person who has wronged so many people and has much to make up for- she has no real right to indulge in personal relationships.
Faith could just be a workaholic, or preoccupied with finding meaning in her life, or busily and selflessly making amends. Possible, right? Not all characters have to be defined by who they are currently dating.
at some point Faith deserves to have someone who loves her, unconditionally, more than anyone else, because I don't think she's had at in her life.
Hell. to. the. no. I'm so sick of every character always needing a relationship or a love story. I want a dam character that shows that you don't need that stuff to be happy. Seriously, she's the only one that's always been equally fine being single compared to being in a relationship.
Slayer or not, Faith is certainly human, even if a very powerful one, and it is a medical fact that the kind of long term stress that she has been under, probably longer than any other Slayer in history, including Buffy, who we clearly saw at least once, between Seasons 1&2, spend the summer with her father, and again, between Seasons 2&3 working as a waitress in LA (apparently without doing any demon fighting all summer, or Giles and the Watchers would have been able to locate her) and between Seasons 5&6 in Heaven, all conscious breaks from her Slayer duties, whereas the only time away from the job that Faith had was unconscious coma time and prison life, complete with its own unique stresses.
The term that describes this is Post Traumatic Stress Disorder
