should I be mad

My boyfriend asked one of my best friends if he can pick her up from school and we all three hangout ,I was kinda upset bc he didn't ask me before he asked her. Oh btw we were all really close at a time bc she dated his best friend and now they broke up , but I'm not like that with his friends ya know . But I feel bad bc I got mad at him and he said that he was as trying to do something nice for me . But the thing that got me mad was that my friend didn't even tell me he was picking her up .im I acting ridiculous or is it normal to feel this way
