Am I wrong?

Ladies my son is 10.. He's my biological and my husbands step son in which he's raised him since he's been 8 months old.. (No he doesnt see his real dad) long story short my husband is a complete jerk to him lately... I wanted to get my son because he's at his friends mind you he doesn't stay places and we told him if he got scared we were not going to pick him up... Well here it is 10 pm (mind you my husband works third shift so is use to driving in the night) I asked him to go get him and he flipped out on me saying NO IM NOT going to get him. We told him if he wasnt gonna stay not to go. Well I told him I'll go get him then because he's crying and uncomfortable where he's at. And all hell broke out threw his protein bar. Accross the room saying "I'm sock of it" mind you my son is a HANDFUL at times. He has odd and ADHD ... I guess what I'm asking is am I in the wrong for wanting to get my son even tho I told him I wouldn't?!
