Looking for opinions. Background is Dh has one sister, we've never really seen eye to eye on much over the ten years we've known each other but are civil and I try to be friendly at events we end up at. She and her Dh have very different approaches, beliefs, lives than us. She has two dc the same ages as my two, 6&8 in the same school and live the next street over. Mil and fil have all our DC for a day every fortnight and they get on really well. Her and dh work full time from home, my dh works full time and I work part time.
My relationship with dns is good, I take them to extracurricular activities when asked, have them over every school hol and some weekend days, sleepovers now they're older etc. I make sure they know they're always welcome at any time and loved.
My aibu is that dh is questioning why I do this, he sees it as me being a bit of a doormat because he sees that the parents are CF and aren't responsible (think go to and from school unsupervised, to the park etc) and want the dc passed off (they have a lot of help from her dhs parents too so don't really seem to spend quality time with the boys) and yes the dns can be a handful and from time to time theyll come out with their parents opinions and argue with my dc (in these instances of usually say it's ok to believe different things, have different opinions etc and change the subject) but dh sees it as bad influences over our dc. They're generally good kids, and I don't do it for the parents I do it for them as they love our fun days and our relationship and their bond with my dc, so pretty selfish when you break it down anyway.
They're sleeping over tonight so sil can go to a concert and dh isn't happy. Technically they're his dns but I see them just as much mine as my dbs dc so I've been doing it all single handed and don't expect him to run around after anyone like I do. He's out tonight so won't intrude on our time but I feel awful on everyone now. So aibu in spending the effort when it doesn't (usually) involve dh anyway? We don't get help or nights away and it's never reciprocated by them if that makes a difference.
