He knows I like him. How? Long story but this aint the question. this boi be undecided !?

There is nothing in the column of signs he doesn't like you that would strike me as him not liking you. He is nervous about his feelings. You need to flirt more with him like get closer to him or another option is you can ask him out on a date. If you are concerned about the second idea then just start working on the first. If you get more obvious in your feelings towards him and hint more frequently then there is a good chance he will ask you out.
