Nope! Her values were absolutely NOT the reason! Not at all! You forgot to mention that:
A.) her father abandoned her before her birth. (because i'm sure there's some statistical significance with pre-birth abandonment and 25yo holier-than-thou virgins)
B.) her mother had a broken heart. (and definitely NOT post-partum depression, or clinical depression, or any number of issues that gave her mom the sads)
C.) Mia. (because being witness to people's horrible personal choices turns you into a bitchy, judgey little saintly put-upon girl-woman who's so emotionally stunted that you lock yourself up in your own chastity belt and punch anyone in the throat who asks about the key. metaphorically, of course).
Yeah, Lola. You full of shit. STINKING shit.
