Well, there's just not enough information in your question to properly evaluate it.
If you had an argument before, he might have said it in the heat of moment.
But we don't know anything about your relation and how you both treat one another.
In the end, he knows the answer better than we do, so the most reasonable thing to do is to just ask him why he's unhappy.

There is no information to give you any kind of advice. How did he hurt you? What was said and in what context? If he isn't happy he can't force that; and like you deserve not to be hurt he deserves to be happy.
So if you want to give a little bit more information people may be able to give some advice
