This family will tell you they have had many years of family meals for birthdays, christmas, bonfires, celebrations etc all cooked by me, washed and cleaned up by me, and hardly remembered by me (except the exhaustion of course). Even weeks holidays with 12 or more people all catered for by yours truly as whenever I needed help they always had somewhere like the beach to rush to or a hot shower (mine was always cold as I was last, thats WHEN I could get in a bathroom. Then......whoopee I suddenly decided it did not mean I didn't love them, it meant I wasn't the doormat anymore. The final straw came was DS,DIL and grandson stayed for a week and I waited on them hand and foot and I was tired at the end of the week and I popped by head around the door to ask someone to wash up.....DIL was just painting her nails and DS was in the shower. I flipped...(no need to tell you the exact phrase) but enough that once I had lay on the bed to calm down and came down, kitchen was spick and span and cup of tea ready. I think they come to expect it but if you explain nicely enough is enough AND stick to it, they get the message
