Mixed Personalities?

Ok, so let me give y’all a backstory. Me and this boy let’s call him James was friends right. James been liking me for months so I finally decide to give him a chance. We wasn’t official but he was acting like a perfect bf. Gn/Gm texts, walking me home, ect. So summer hits and we start to become distant so I end it and we stop speaking. School starts and after speaking again I asked him could we try it again. This time it’s different tho. He barely texts me and when he does it’s dry. He walks me home but only so he can “wrestle” me. I asked him did he just wanna stay friends and he keeps ignoring my question. Today we was in the same class all day and I asked him the same question and he kept ignoring me just trying to “wrestle” and when I said alright ig I’m single he said “you been single” I just need y’all help because idk if I’m tripping or not but I find it so crazy how he can go from one type of way to a whole other type. My plan was to just ignore him because whenever I do that he seems to try to wanna talk/flirt with me and if I ignore him he keeps doing it till I talk to him. Should I just text him and say I’m done and stop speaking to him? Lmk thank you!!
