He hasn't called me. Should I be upset?

Anonymous
my boyfriend of a year went on a cruise with two of his friends. I'm not really mad about that but he hasn't called me once. even though he doesn't have a cellphone don't you think he could have called me off of his friends or something? he's been gone for 2 days and no phone call. I've been a wreck. would it b wrong of me to tell him it makes me upset that he wouldn't trey to get a hold of me? I'm upsst.
