Guy's Behavior

Can you please help me about my crush?

The thing is he does know me because my ex friend told him i liked him but he hasn’t said anything to me or did anything, however when my friend was chatting to him about me he pretended he didn’t know who i was? Last week, he gave me food he made and asked if it was good and we was joking around and the other day he threw water at me i threw it back like in a joking way. This week he brang it up again to his friend and i chased him and he ran away and we was playing with eachother after that the next day when i walked past he was staring so i said what and he said what back and when i was walking way he laughed then he brang the water thing again up bc i wet him a lot. I don't know whether he likes me or not bc today when another girl walked past him he was okay with it but when i did he kinda like walked away. Can you guys help me figure out?
