Is it normal i like him because of this reason?

I've been talking and getting to know this guy who I knew before we got romantically involved with each other. I've always found him interesting and finally we got the chance to see what's up between us and take things slow. There was always something unique about him and I guess the reason why I like him is because he's been through a lot and he's just the opposite of me. I actually met him right after he came out of jail and we talked about a lot and he said he found me intriguing too. Not sure why because compared to his life, my life is pretty boring but for the reason I was brought up in a good environment, a little spoiled, and never was a huge troublemaker. In contrast, he doesn't really talk to one of his parents, he has broken the law a few times but regardless of all that, as a person he's a cool guy and not to mention wise. He just does dumb shit but that doesn't mean he's dumb. Why does he do it? I don't know he says he's just always been surrounded by those "types of people." He even asked why would a girl like me (clean and innocent) wanna get with a guy like him? I told him what I just said here but I didn't tell him I don't plan on settling down with him because at the end of the day, were completely different or at least our lifestyles and I know that's gonna get in the way.

But besides that, I do like him because he's the opposite of me; street smart. It's kind of like rose and jack from titanic. How rose found jack interesting cause he was real and street smart where rose although had material things didn't have much to offer and she knew it which is why she liked jack. He taught her what life is about. But going back to me and this guy, I feel like if I try and pursue something with him, I'm only asking for a lot of drama. I feel like I'm playing with fire at the moment and I should walk away but I can't help but find him interesting and like him.
