Boyfriend problems..

Alright so I need help. My boyfriend has a lot of friends on his PS4 okay.. and one of them happens to be a girl he talked to briefly and liked but it didn’t work out because it was long distance. Well today he tells me she asked him to play a game with him and he said he had to work and I asked him if he would have still played if he didn’t have to work and he said maybe. Well this infuriated me. Am I right to be mad? Or am I just overthinking and it’s nothing. Please help I am about to flip my lid and I’m really pissed off.
