Heeeeyy could he like me?

I hung out with a guy I like last night and his step sister. He flirted with me all night but I've been played a lot haha so I just want to make sure he isn't playing me. Ok so, there would be some moments when we would just look at each other and it would be quiet. It's very awkward. And I don't know if he was trying to show off but he is always talking about how sore he is from working out and how strong he is. And then he would randomly do push ups in front of me and ask if I could do as many as him. And he always teases me, like ALL the time. And he would jokingly call me a loser and retarded and stuff. And when he was looking through my phone my screensaver says "hotties" and it has a picture of me and my friends, and then he looked up at me and smiled and said "this isnt true we need to change this!" And also he would playfully kick me and squish me against walls and push me in the snow. Haha and lock me in dark rooms and not let me out. And he would steal my hair tyes and wear them. And he would always mimick me in a girly voice when I'm talking or make fun of something I did. And I had a feeling that he wanted my number because he would always look through my phone and then he ended up getting his phone but then my phone died. But we didn't like flirt all the time we would have serious conversations too. Haha ya, so could he like me??
