Hello,
to be clear, I can't stand my grandmother. Every time you do something meant nice, she's making bad comments, every time we meet, she's criticising something and on the other hand she's offended quickly if you don't play as if the grandmothers are the most importand thing in every childrens life. I always tried to not see her too much and search for not offending excusions why I had no time to talk to her (my parents live in the same house as my grandparents so it wasn't too easy). For our wedding we planned to have just a small gardenparty with 20 people in total, just brothers and sisters, parents and 8 closest friends. My FHs grandmother in fact will be there too, because we will do the gardenparty in his parents garden and his grandmother lives in that house as well. Of course, I can tell my grandmother, we wanted the party as small and relaxed as possible, so every further person would make it bigger than we want, but this wouldn't stop her from making a hell of it and be very very deeply offended. She could never understand, why I don't just enjoy big parties as much as she does and she would only see the intent of saving money in cutting the guests to 20, not the intend of just disliking big crowds and wanting a relaxed athmosphere. And in her mind, not inviting her would of course just mean that she is completely indiffent for me. How can I explain to her, that I do not want her participate in my big day (surely, she would ruin it for me) without having to prepare for the hell?
