When is 'Overprotected' too "Overprotected"?!

So there is this one class I go to for my Graphics Design course and I am so confused. It is a Jewish College but Goyim-non Jews seemed to have enrolled here as well because it offers financial aid and what-not. There is this young married lady that joins our class but she is always 'brought' by her husband. She is Muslim, which does make it understandable, the men always are hardcore-in-charge-or-else type. I feel it's unesassary and just not normal. He peeks his head in to make sure he agrees with the students and teacher. It makes sense, a little, I guess, but when is overprotecive too much??!!?!
