Hi NoLonger,
It can and will change over time, if you continue the reading/working/learning you're already doing. You're not "doomed" to love only cold or angry or avoidant or commitmentphobic men long term, and your "tastes" really can change.
It began to change for me during a process when I began to recognize my blind strong attraction to hurt -- men who were tragically hurt themselves and manifested that hurt in a way that would hurt me (aggression or, more often, unavailability in myriad ways, so I withered w/loneliness). My empathy drew me to their hurt, my confusion of love with self-sacrifice (still) had me stay far too long.
I used to know that if you lined up six men in a bar: 5 decent, reliable, kind, unremarkable-looking men, and 1 good-looking "bad boy" with a sneer on his face who had deep fear and dislike of women...well, superficial me, I went for him. I'd practically herniate myself trying to get that one to love me.
BUT IT'S CHANGED. Put me near that same lineup now and I might pause or feel wistful for a brief moment on meeting "bad boy" (part of me would remember my old pattern of craving "fusion" with a cold man, from the get-go) but today I would quickly have a REAL feeling of being repelled away from a man who would act out his hurt by hurting me...and feel more drawn to the kind ones, the funny ones, the gentle ones. And drawn to them gently, slowly, without the need for speed.
Today, I dream of a warm handclasp and shared glance and good steady human with a warm heart and functioning wit. Back then...some bodice-ripper cover where the pirate is ravishing the twit, I mean, the heroine.
I know passion can kick in with kind people, too, given maturity and time.
I've just come to recognize that compassion is more important to me.
Hops
