We live in the house once my in laws lived. Family has a tradition of having summer BBQ , when in laws wedding anniversary happened. There's also Christmas party each year. My in laws died over the decade ago, but tradition stayed on. Each summer and each Christmas family gathers in our garden for a party. I accept it, but I want to go on party too, not to be host all the time. DH doesn't get it. He says I'm jealous and mean, as family brings food, so it's only the same premise and it's tradition. It was broken only once, when our son was born and I firmly said I'm not having party with one-month baby in the house, our boy was born in June. BBQ was hosted at his sister's. Now his brother asked him , without me knowing, he wants to host his wedding anniversairy party in our garden, as his own garden in tiny. DH said yes. I don't like it, BIL didn't ask me, just DH and he said yes. When I said I want to go out too, not only have parties hosted at my garden, DH got angry and said agian I'm jealous. It's not even I don't want him to have a party in my house. But it ALWAYS in my house, never at others, and DH has 5 sibilings. AIBU? I don't know, how to approach it.
