ADVICE NEEDED

So when something is bothering my boyfriend he shuts down. He likes to go days with out speaking to me. Usually the situation is family or school related and although I try my best to give him space it really bothers me that he shuts me out and ignores me like this 
How can I handle this situation I don't like going days without speaking to each other 
He always says I take things to personal but o just see something wrong with that I know as humans we need our space but idk
