DH has invited his sister to stay over Christmas, we don't really get on, she's usually a bit absent, lives away and only sporadically in touch when she wants something, often money, has been very cold/rude with me at times which I've tried to let roll off my back to keep the peace, drinky, has been known to nip down the end of the garden to smoke a joint, but would otherwise be alone over Christmas and DH doesn't feel he can say no to her. Selfishly, a proper festive dampener on what was planned to be a first cosy quiet family one just the four of us with all other family having made other plans.
I in turn decided to take my DDs (not DP's daughters) down South to my brothers so they can have some fun with two sets of cousins, and my mum and elderly aunt who will be there. A big jolly old fashioned Christmas. DDs happy with this arrangement, which I organised as they weren't filled with joy about hanging out at home with DH strange sister.
DH is upset with me for bailing on him and leaving him with his sister, as he thinks they will have a shit time. I am inclined to agree, as it will basically involve watching her wordlessly motor through the drinks cabine. I'm a bit upset with him for agreeing to her sort of gatecrash our christmas and completely change the vibe for the DDs especially. I am upset not to be able to spend Christmas with DH but felt if I could save things for the kids I should do that? And now it's kind of done.
Is either of us being unreasonable? Have I been selfish to bail? Or was he unreasonable to change our plans and invite his sister? Is this just how it goes with weird family that you don't really want to hang out with?!
