Your boyfriend should not be angry with you, just because you talked to another boy.
However, a lot of boyfriends would feel concerned or threatened, perhaps.
He may feel jealous ~ worried that you will leave him for the other boy.
Anyway, it's understandable that he feels a little jealous ~ but of course you have the right to make new friends.
Explain to him that this is just someone whom you met and got on with, and not in any way a threat to your relationship.
(It isn't, is it?)
