I really need some advice please comment

So I’m 13 and I like this boy in my class and I think he likes me back I mean I’m scared to be in a relationship but I want to know if he’s telling me that he likes me. so all last week he’s been getting me really mad because after lunch I’m trying to put my combination in my locker and then when I’m about to open my locker he turns the knob or tries to close my locker when I open it on Friday i almost punched him and he thought it was funny I told him that he has been making me late to history class and he still thinks it’s funny and then on Wednesday at the end of the day I was closing my top locker and I like to close my top locker really fast but he knew that I was closing my top locker and he put his hand there ( he didn’t even fall or anything and he was just closing his bottom locker) and I accidentally slammed his fingers in my locker he acted like he was hurt closed his bottom locker I closed my bottom locker ran after him asking if he was ok and kept on saying sorry I kept on looking back at him when I was walking to my bus bc I felt really bad and before I went on my bus he looked back and smiled at me. Is that some of the signs boys show to tell you that they like you?????
