Am I right?

My boyfriend is currently in China for a University business trip, he went out clubbing which I didn't really like but whatever he can do what he wants and he's in China for the first time... When I was scoping through my Facebook feed I found out my old friend from primary school had passed, I was devastated and very upset, I messaged my boyfriend while he was still out, all he said was I'm sorry and left to continue his party night... I'm let down, I went to him for comfort and I feel stupid thinking he'd be there no matter what, he was drunk at the time but just because your drunk shouldn't change your priorities or morals... Do I have a right to be mad?
