for me, the comparative thing was easy to start and i was really into him for a few months.
Then after he let his guard down, he started to insult me constantly/do things that offended me every hour or so. he had no idea, and thought I was wrong to be offended/refused to try to change. Followed by him trying hard to change, faking being what I wanted, adn eventually that fell apart.
All in all, icky.
But still, there's a lot of mutual "hmm that person is interesting/mysterious, etc."
Followed by "why the heck are you doing x? or y? or z? ahhhh!"
