Genuinely unsure...
My inlaws do not seem to like me very much, it used to annoy me but now I just think we are very, very different.
They are due to visit us and DC for first time in years. We have a very small house, DC have significant needs. There will be a lot of adults all crowding the DC and fussing.
I mentioned to my parents I might just invent a reason to go theirs and leave DH, inlaws and DC to it. DM thought it was a good idea, DF thought it was completely unreasonable.
So as not to drip feed, there is some history of me feeling like I put in all the leg work to facilitate inlaws' relationship with DC with me being kept around as a nanny for the difficult tasks while they ignore me and talk about what an amazing Dad / husband / human DH is for the most basic things (DH thinks they're ridiculous for this too).
YANBU - escape to your own parents and hide from the tension.
YABU - it's just one weekend, suck it up and muck in.
