Guy disappears and reappears, why and what to do?

I have been seeing this guy for 2 months now and 2 weeks ago he just dropped off the face of earth. Last night he texted me and said there is something bad going on back home (he is not originally from where I live) and he nearly had to go home to deal with it. I like this guy but what he did (disappear) was disrespectful and made my heart died a little, like, how much does he care about me? Or disappear is normal for guys when they are dealing with something serious? Should I trust him and put up with it? But he could have told me he needs time off before he vanished! What to do?
