Is it normal if i like it when he's a jerk to me?

Its a different type of jerk. Not like being disrespectful to me, but more in a funny, mutual way. If he's not mean to me at least once a day, there's something wrong. Once he's mean to me, I feel relaxed like he's being himself with me and comfortable with me. That's just who he is and I love it. He's sucha kid and sucha douche sometimes but at the end of the day, I take it as he's comfortable being himself with me and what's better than that? But he's also mature, knows when to be polite, smart and just has common sense. Its like two in one :) Before we got together, we were just talking so we were single and free to talk to any one else. So during a few parties, gatherings, or whatever, yeah I'd spot him with another girl (s) but in particular with one that I knew he had a thing for. So it was kind of like a competition but not really. It was me or her. And we were all acquaintances so in a group I'd observe how he was with her or any other girl, and he would hold back his side I like as if he wasn't able to express himself with them like he does with me. At the end of the night, he would come with me and we would watch Netflix and laugh the night away. I will never forget the moment at this party, I was with my friend and I turn around and catch him staring at me, smiling. That is seriously the best feeling ever ! It's like I make him feel good and he doesn't know how good I feel about him ! Our sense of humor is what connects us the most. It can be mean humor sometimes but thats where we connect the most, haha. So I feel confident when he's being a jerk to me, cause he's just being himself. If he's nice like for a whole day and just stiff, I know somethings on his mind and he's not being himself.
