angry ?

I just got mad at my boyfriend for going out with his friends a gay guy and a girl who he's known for 4 years . I got mad because I asked him if he could come here after he went over to his cousins but he's been tight on money so I understand that he can't drive 15 mins to see me but he gets home from his cousins around 11 pm and he tells me he's going out with his friends. I hate when he goes out late I don't know why.. But is it wrong how upset I got ?
