We were all in the gym one time and I was sitting on the floor in a circle with some of my friends. My crush and his friends were playing basketball. My crush threw the ball and it accidentally hit my in the head. He kept apologizing and apologizing to me but I just laughed it off and said it was fine. This may not seem special, but he accidentally hit another girl in the head and he didn't act as worried as he did with me. He kind of laughed at her. And whenever he is around and he says a cuss word (which he doesn't do often) he kind of looks scared and then apologizes to me for cussing in front of me. These aren't the only things he has done but I have asked many questions about other stuff he has done before and have gotten positive answers and I have wondering about these.
If he's only apologizing to you for everything he does, and doing different things around the other girls, sounds like he likes you. It also seems he's doing these things to get your attention, and it seems to be working.
