Does this mean he like me?

I've made a group of friends and we became really close and I became close with one of the guys. I noticed that every time we hang out he sits really close/next to me because we both became super comfortable with each other. When he sat next to me while we were all having a convo he leaned in towards me and had his arm on my chair and we unintentionally touched each other as he was trying to talk with other people. I've noticed he tends to do this a lot when we are in a big group.

Does this mean he like me?
