We tend to alternate Christmases, one year my dh's family come to us + the next year we stay with them. My family live locally so see them Christmas + New Year.
My dh is absolutely fine on the years his parents come to us, but when we go there he finds any reason to sulk, ie, "feeling under the weather, too much to drink last night, tired from stress of work leading up to Christmas, etc".
We go there with our 2 dc's, + my dh is fine for the first day or so then after that the sulks start. What happens is his mum always runs around pampering him, "Can I get you something, Do you need some peace + quiet?", etc!!
I've learnt that the sulkier he gets the more I ignore him, + concentrate on enjoying Christmas with the dc's + everybody else. However this time I've already told him clearly, "No teenage strops", he is over 40 FGS!! He's now saying I'm causing tension before we even get there, + has gone off sulking already! I'm glad I said it as I think he needs to realise. Does anybody else's partners tend to react like this when back in their childhood home? The rest of the year he's absolutely fine with everybody!!
