Yeah except for the "throw out everything and but new ones" part. If she asked for a particular style on date nights, that would be one thing. But I sincerely doubt that she every bra and pair of panties she owns is a matched set of lingerie.

I hardly think boxer briefs are the equivalent of lingerie.

That's a fair point for OP to make, and sometimes when someone makes a request for what they want, they start with what they want and can talk about it and compromise if the person they are talking to has conflicting wants.

If OP didn't care at all about wearing briefs, he might have just switched without a word. This request is only unreasonable because he doesn't want to and the decision should factor in his wants, which she would not have known before her request.
