My boyfriend is going on a trip with his friend straight after I come back from mine?

Anonymous
I’ve been on a 3 week trip to see my dad. I arranged to see my boyfriend the day after I come back. He told me yesterday that he’ll be going on holiday with his friend abroad when I come back and he doesn’t know when he’ll come back. I’m kinda upset with him. Is it something worth getting upset about or should I overlook it?
