My first husband got angry at me once when I cut my hair and didn't ask his permission first. He said "opinion," but our dynamics being what they were, he meant "permission."

If I wanted to cut it now, I would merely tell my husband I'm going to. Or, I'd just do it. He knows it's my hair. He wouldn't say a word.

I think the ex-girlfriend's reaction was way over the top. No partner should dictate to the other what style choices they make.
