Let's see: trying to interfere with his duty and obligations and encourage selfish behavior in him (contrast to Nynaeve's refusal to allow Lan to violate his sense of honor for her sake); verbal harassment continuing now that their relationship is acknowledged; refusing to allow him space that he needs; driving him to take measures in their relationship that he feels are wrong and heaping guilt and shame on top of him, because of her ignorance and refusal to adapt to other customs or cultures (and yes, he's guilty of this to a certain extent, but for Perrin, his guilt is mitigated because he never sought to leave home and travel in foreign lands, and certainly never pursued a relationship with a foreigner despite the other party's apparent lack of interest; Faile did both, and if you are going to do that, you damn well better learn to adjust); and treating what is for him a vitally important mission to protect his home and family from deadly enemies as a lark and recreational adventure. It is to her credit that she stood by Perrin after learning that they had come too late and his entire family, from senior citizens to nine-year-old children were DEAD, when slinking away in mortification and being ashamed to show her face around him after the way she behaved regarding the journey there would have been more understandable responses!

Faile has spoken! Forget barging in where she is not welcome (as she has been doing since the first day they met), she has declared an interest, and the hell with Perrin's wishes in the matter! Seriously, WTF?

Who the hell died and made that her rightful place? Her RIGHTFUL place was at home, doing her duty by her family, rather than leaving them stuck doing THEIR duties with visions of their 16-year-old daughter raped & murdered in a lawless southern gutter. She's a selfish bitch at this point in her life, whatever her good points, and she is later redeemed by her relationship with Perrin. The character improvements that are brought on by her relationship do not excuse her deplorable tactics in facilitating that same relationship.

Because she's matured a lot, having been on the receiving end of abusive treatment, and been forced by his example to live up to responsibilities, and learned to accept her responsibilities through her own efforts to teach him the same.

Yes, and a pox on you for making me defend him!

In all seriousness, if you reverse the genders and set this in modern times, no one would fault a woman enduring what she put Perrin through for seeking a restraining order. She behaves like a spoiled child, in spite her self-image as a tough, brave adventurer. In her own way, she is little different from the braggadocio-spewing Hunters Perrin encountered in the village where they first met. The fact that she is prudent enough not to attract attention to herself as a young attractive girl with obvious money traveling alone does not change that she is just as quick to seek vainglorious adventures and fame, that she treats others' sufferings or peril lightly and casually and that she is manipulative and obsessive and prone to imposing her attentions unwanted. How humorously quirky would anyone have found it if Perrin had gone into her room to watch HER sleep at night, and made comments about those body parts she bared in her night-clothes? What if Perrin called her "Cute butt" or "Airhead" or "Danger groupie" ? Faile's references to his unclothed appearance would be just as crude in that setting as the first name is to a woman in ours. And of course, the circumstances under which she comes to encounter Perrin & company are rather irresponsible as well. It all works out that she finds a good husband whom her parents come to approve of, but she could just as easily have run afoul of people who sought to use her against her father and cousin. People are really quick to jump on the other major noblewoman of the series, Elayne, for taking risks, but she is a Green Aes Sedai, and her duties include fighting Shadow-sworn channelers. Faile has the same obligations to house and country, and not remotely Elayne's excuse of professional obligations.
