We live quite far from DH's family and, after a couple of crazy years when the DCs were small we have mostly had an open house but no travel policy at Christmas. This has meant that some years we've had PILs for Christmas and then other family for New Year. There is a chance we might be doing this again this year and I really don't want to but DH thinks I'm BU and unwelcoming.
My reasons are that I feel like it just adds a whole additional round of cleaning, shopping and planning as soon as Christmas is over. Time that I'd prefer to spend just relaxing as our term times are so busy. Also, I'm a bit of an introvert so find it really tiring to have another round of socialising after all the Christmas stuff.
There is a bit of a back story that I feel that his family don't visit very often and it's always visit on their terms rather than fitting in with us so am perfectly prepared to hear that I am BU.
(Just to add, although I'm a new poster, I've name changed since the security thing and have been around for ages, though always more of a lurker than poster)
