For some context first...
Christmas day - Me, DH and 2 DC at home, cooked together, wonderful chilled day.
Boxing day - At my SIL (DHs sister) all together, another lovely day. We traditionally go there every boxing day.
26th - we host my DHs brother and family. I cooked a roast.
27th - I host DH's other sister. DH goes golfing for the day (fair enough, it's his Christmas holiday too)
Today - DC say "what time are we going to your friends house?" Dh pipes up looking miffed "oh you're ditching me then to see your mate" (he's also welcome to come, DC will come with me and they're very friendly with my friends children)
Aibu to go?
In my eyes the last few days have been spent with his family (I saw mine the week before Xmas) and I'm not begrudging spending that time with his family, I get on very well with them. Better than him in fact lol.
