I have spoken to DH about it but I'm not sure whether I'm being overly precious.
DH has a hobby which he loves. I have no problem with this in itself, even though it takes up a lot of his energy.
He also enjoys going to events too and often goes with his father, brother and takes our 2 boys. I have no interest in going, no interest in the event and don't really want to spend the day with DH's family in that way.
However DH thinks he's doing me this massive favour by taking the boys out for the day and allowing me 'time to get stuff done'. This sounds OK but in practice, it means I spend the day doing housework, running errands and cooking Sunday dinner whilst DH has a lovely family day out.
I feel like Cinderella. I got very upset last week when I suggested a night away (just me and DH) but he said he'd rather not as he doesn't like travelling if he doesn't have to (drives a lot for his job) and would miss the DCs. He's driven a 3 hour round trip today though 
Another part of me makes me worry for the future. Although I love the fact that DH and DSs might share a hobby, which will mean they want to spend time together when they are older, I'm also very conscious of my MIL who was often excluded from conversation etc because she didn't share her husband and son's passion. I know it often upset her.
I've told DH that I want the days out to be reduced and that we need to spend more time together as a family. We then planned a day out next week and he said he'd ask his Dad. I said no - it was to be just the four of us. But now I feel a bit mean.
He says that I never want to do anything at the weekends which isn't true- it's just that there are things that NEED to be done, and we should be able to do them together and then have a good time.
