Meeeeh I can sort of see where she's coming from but really, is it any of her business who's going to be there and in what gender combinations? It's kind of obvious that a spouse or partner is very different from a friend, and sometimes you want the company of one sans the other. Dorkiness has nothing to do with it.

One assumes she can trust her husband not to trash-talk her in front of his buddies of either sex - if she can't, they have bigger problems in their relationship. All she did was admit her raging insecurity. Yuck.
