NEED ADVICE PLEASE MIA BF

So my boyfriend goes back to college this Saturday. 
He's been in a mood because of some family issues and he shuts down. I haven't spoken to him since Tuesday he hasn't called or txt. 
Last time I saw him was Monday. 
I am mad because this is his last week home and I wanted to spend time with him but he let his family issues over crowd that
Do I have right to be mad ? 
How wud u handle this situation ?
