Does this happen to you?

I agree that the combination of a huge house, never inviting people over, and throwing parties at other people's houses is weird. OP, I agree with you, and please don't rewrite your post.

 Now the question is "What do I do about it?"

Your husband needs to say ""Oh that won't work for us" next time they propose a party. And he needs to repeat it over and over.
