Does my step cousin like me, or have some attraction to me?

Okay, this all may sound a little weird, but hear me out. So when I was little, I had a crush on my step cousin. To make things less weird, we are not related by blood of course, but only by marriage. His personality was so funny and the jokes he made always made me laugh, and the thought that he wasn't related to me so it wasn't a huge deal. I guess that's what caused me to have a small crush on him. When we got older and I grew into our teenage years, I grew out of my feelings for him and just brushed it off as a simple "cousin crush" and started liking people in school. But then, he started acting weird around me. I think it started when we were going on 13, I can't really remember exactly. But he started acting different. One time when we were at my step grandmother's , he walked up behind me and started playing with my hair, then picked me up bridal style. I was confused at first, but figured it was nothing. Then he came over to our house, and when I would go to my room and lay on my bed, he would always run into my room and lay on top of me, resting his head on my chest. I would tell him to get off, but he would stay there awhile. There were other times such as me restling with him and having my arms around him to throw him down, and he would look at me and hint that I was being romantic with him and laugh. Playing truth or dare, I would say I liked someone and he would not rest and kept asking and asking who exactly it is. He has slept in my bed with me when he could've slept on the couch or with his actual cousin, and has tried to get me to admit I still have a crush on him or he's good looking, and has said it would be legal for us to get married if we wanted to since we aren't related. He has done many other things, and I'm not sure if he has a crush on me now or not. Guys, or just anyone, can you tell me what you think and why he may have been acting this way? He doesn't do it much anymore, but I'm still confused.
