CL has your wife always been like this or is it since you started peicing?
I agree the party is a good sign but not if it makes you feel you need to be someone else in your own home I would find that disrespectful.
I cannot see how it could not have something to do with you after all she is your wife and you her husband. An obsession with her privacy would surely mean she wouldn't even invite people to a party.
I hope things work out better after the trip.
