Perhaps I missed it, but what happened with the boyfriend in the house scenario?
		
		
	 
It was fine.  My boyfriend is one of the most laid back people I know, so he was understanding about it.  Of course, I was pretty upset when I told him so he really had no way to be other than calm.  At the end of the day, we really didn't mind the time apart - he and I live and work together - we just would have preferred it to have been our call rather than my father's.My mom actually called a couple of days before Christmas and explained that it was because they really wanted my sister to have a place to sleep on Christmas Eve.  My parents only have two guest rooms and my boyfriend and I are not allowed to sleep in the same bed yet.  So, that was their reason.  Allegedly.
He came to their house around 3:00 Christmas Day and spent Christmas night - and we all had a good time.  
He re-asked Mom and Dad for their blessing (he asked back in February for the first time), so I think that helped things tremendously.
