to go Victorian on somebody

[coolfool_sin]

Irving Wallace is one of my favorite writers. Last year, I read The Three Sirens. To me, this is a good book, like the others written by him. I still can't, however hard I've tried to, grasp the exact meaning as follows:

"Since when have you gone Victorian on me?"
"Since my husband went Victorian on me," Claire shot back.

As adjective, Victorian, here, means:
1. of or relating to the reign of Queen Victoria
2. of or relating to the attitudes and values of this period, regarded as characterize​d esp. by a stifling and prudish moral earnestness

I'm wondering if someone here would give a hand to re-phrase the above in another way?

Thanks a lot.

Perhaps, if you provided more context, you might get answers. For example, what happened or was said immediately before the opening remark above? Surely that would give you a clue as to which aspect of Victorianism was involved.
Similarly, we don't know what Claire's husband actually did. He may, for instance, have become all Victorian pater familias and started to tell Claire what to do, rather in the manner which lots of Victorian husbands did. She may then have become all submissive in her dealings with others. There are many possibilities but, without more background, we cannot tell.
