The part of twisting you around to be the bad guy sounds familiar. Mine was a rocky hs into college relationship. A couple of decades ago. Certainly, in my own lack of maturation into my early adulthood, as far as, understanding healthy relationships and communication myself, it was a most confusing time. The damage led to some further not so well relationship choices, ones in which I learned to not speak up/speak out.(in those relationships, learned since because of the outcomes of full scale abuse)
I wish I had advice about friendships to give some type of insight. But as far as how you describe him, yep, yep, yep. Cannot say I've ever since bothered with any man since that is like that.
I certainly wouldn't call you foolish for seeing through new lenses what it was about him.
