The wedding is a long way off so if this wasn't family-related I wouldn't care but I have an issue that I know what I want to do but I'm not sure how to go about doing it.
I have a cousin who I'm very close to. We could be sisters. She's had a pretty difficult childhood but has turned out to be a wonderful person. Her mother has had drug abuse issues and made several bad choices that now have her in prison. She won't get out until my cousin is 35. While growing up my cousin lived with her grandmother. Her grandmother loves her very much and took care of her.
A few years ago my Mom and her grandmother had a falling out. She said some very hurtful things and my Mom chose not to feed into it and blocked her number and email. Soon after her grandmother had a stroke and had to be hospitalized. My cousin took it hard. The grandmother ended up needed round-the-clock care and had to be moved to a home. We helped my cousin sell the grandmother's house and sell off the household items to help her pay for the medical bills and she moved in with her now husband.
At my cousin's bridal shower her grandmother attended and when she saw my Mom she began hissing and cursing at her. This made me very upset and angry but I knew that her grandmother gets confused sometimes and forgets where she is. Despite her recovering from her stroke she still remembered her hatred for my Mom. To prevent any drama on my cousin's wedding day, my Mom hid in the back so the grandmother wouldn't see her and get upset.
Now getting to the point, my cousin left me a message and asked if I was going to invite her grandmother. Honestly I wouldn't have a problem with this if she was able to keep her opinions to herself and stay quiet. But there's no definite way that she won't start yelling at my Mom the second she sees her. I would like to assist her grandmother but I will not have my Mom hiding in the back at my wedding!
How do I tell her "Hell no!" but in a nice way that doesn't hurt her feelings?
CN: Cousin wants to bring grandmother to wedding who suffered from a stroke, forgets her bearings, and curses my Mom out the second she sees her. How do I tell her no nicely?
