When a guy doesnt talk to you anymore does that mean he is scared to like you?

All i can say is when a guy does not talk to you any more its maybe becuz he likes you in the inside and he is scared to show it to you and the other reason is he really likes you and when you 2 start going out or what ever he is afraid he will be rejected r to mess things up, so you need to start talking to him and if you are shy just ask him questions about homework or assignments then you could connect again and start talking to him.And politly say "hey why were you not talking to me in a while". and if he trys to ignore that question are say idk then he likes you and he is afraid to mess things up of ur relationship or friendship.
