So my grandmother is flying in from another country on her own the day before the wedding. She's 80 and in poor health, i.e. she walks with a cane and has to catch her breath every 20 steps. Although I'm going to pick her up from the airport (which I really wish I didn't have to do the day before the wedding - but she insists), the plan was for her to stay with my parents (her son!) over the weekend in the Airbnb they're renting for the wedding.
Now this is the problem - she's refusing to stay with my parents as she insists she wants to be near me at all times. She has thankfully clocked that the wedding night is off limits, but is genuinely shocked that I don't think it's appropriate for her to stay with me the night before the wedding. I've tried telling her that I will be super busy that day and that I'll be staying with a bridesmaid at the venue - plus that she'll still get to see me a bit during the day AND the rehearsal drinks that night. Granny won't have it though - rebutting every argument and turning on the waterworks (plus saying a tonne of really manipulative things) when she realised that wasn't working.
Am I horrible for not wanting to spend my last day before the wedding taking care of an 80 year old woman that no one in my family likes? How do I relay the inappropriateness of her demands, and make her see that although she thinks I am the one being selfish, it's really her who is being the selfish one? We're currently at the point where she thinks she'll be staying with me by the way, so I need something good!
