Does he like me???

So I have this guy friend and I have been developing a crush on him for a while now. I have no idea how he feels about me though. We text like everyday and usually hang out after school and I think he flirts with me? He'll like play fight with me and we'll talk and stuff. My friend says he's totally flirting with me but I don't know. And the other day he told me that he didn't want me to die😂 ( I was being dramatic saying I was going to die bc of school) but he said I was like his only friend and hes known me the longest and the best. Also last week we made plans for the week after this one. Annnd I asked him if it would just be us and he asked me if I wanted there to be other people and I asked him if he did and he said no.... Sooo I don't know if he likes me or is just my friend😫
