Is it wrong if ur boyfriend has a girl that he knows in his car yet he juts told u a couple of hours ago that he will be taking her some where . Yet when you try to get a ride from a friend at school who is a boy he gets mad and says that you can’t do that because he Doesn’t know the guy

My question is is he on the wrong for having another girl in his car yet I can’t be mad or am I in the wrong for being in another guys car and am I wrong for telling him it goes both ways ?
