Does anybody think Gary from Teen Mom was right about Amber BF changing his daughter?

I personally think Gary is one of the best dads from the whole Teen
Mom series. I'm watching this episode where Amber is acting like its
no big deal that her boyfriend changes their daughter while Gary is
very upset, and I think he's in the right. Amber shouldn't haven't her
boyfriend no where near her daughter private, especially since she
barely knows him. Am I the only one who thinks Gary was in the right
for getting mad?
