Tomorrow is my crush birthday at school who rejected me yesterday and said we can be friends should I wish him and talk to him?

Even though your crush rejected you, you should remain civil with him and wish him a happy birthday and talk to you.
You never know what future holds for you. Yesterday's rejection may be tomorrow's crush as well.
By ignoring him and his birthday, you indicate that you are taking offense for not reciprocating your crush. A crush is not something that just pops up from one second to the other. It has to be earned and he did not (yet) see you as a potential crush.
If you sever communication, you also sever a potential start in a relationship, who knows? Best is always to act friendly, even if he did hurt you by not reciprocating your crush. Good luck.
If I were you, I would just simply wish him a happy birthday and leave it at that.
