Most people are shocked that they allowed themselves to be duped.
They can't believe they made themselves vulnerable to a wolf in sheep's clothing and became their victim.
But, that's the whole point. Predators... physical, sexual, spiritual, whatever... make themselves look not only presentable, but normal and even attractive.
It's their strategy to draw you in, gain your trust, then use you.
Don't be ashamed.
But, be on guard now with your newly gained wisdom to not fall for it again.
