My crush stood really close to me?

Me and my crush were talking and I was standing in front of him. Then he started moving closer and closer to me to the point where I almost fell backwards. I had to catch myself with my foot. He was also making eye contact with me the whole time through the conversation. We weren't even talking about anything to do with flirting or anything. We were just having a casual conversation. My friend was standing with us so it must've been really awkward lol! could this mean he likes me too?
