I can sympathise. I used to dread the invitations but was too polite to refuse. However, now, if I'm put on the spot I'll say "I need to check my diary and that's at home" (if out) or "that date rings a bell - can I get back to you?" And then reply No, sorry, we're not free" (I never give an explanation). Also, I never do it in front of DH as he's always too anxious to keep everyone happy, so he agrees, forgetting what happens when we go (he stands in the corner and doesn't talk to anyone, and then, on the way home, says he's SO glad it's over). Very occasionally I go to family occasions but it usually reminds me why I don't. At the moment, they may be inviting you out of politeness, and the fact that you always go gives them the signal that you WANT to keep receiving these invitations. The only way you're going to break that cycle is to start refusing some of them. PS If it's children's parties you particularly don't like, you can start with those.
