Anne The Sequel - Could be wicked and wouldn't 

She just likes the idea of someone she marries that isnt altogether good, and that there is the possibility of being wicked, but they choose not too. Makes for a little excitement. I wouldnt want anyone that was extremely good either.

Someone that is not entirely good and not entirely bad. Someone who is good but has a little bad side for excitement.

She's saying she wants a strong man, not a doormat.
