I need some boyfriend advice...?

first of all don't break up with him. Maybe he has something on his mind and don't want to talk to anyone. maybe he needs to take a break away from you. Maybe he could be mad at you n u have no clue what u did. there are many reasons why hes not talking to you. If i was you i would let him do what hes doing only for another week and then corner him and ask him whats up. that's if you still care about him. but in the other hand if you break up with him maybe he'll relies whats hes doing. it all depends on you. good luck
