My fiance and are getting married in secret in December 2020. We're planning a REALLY small event, with a total of MAYBE 7 people attending, us included. We haven't told many people, just the people we wanna invite and a few friends. We're inviting my mother and stepfather, mom is taking our pictures and stepdad may be marrying us.
My mother sent me a message earlier saying that she told my grandmother I was getting married and told her 95% of our plans (except the date, but that actually doesn't matter). But my grandmother is now excited and is begging my mother to get her to get me to let her to come. My mother didn't give an answer, saying it was my call and that she skirted answering it to let me make the call.
The thing is... my mother put me in a VERY awkward position. We've only invited my mother and stepfather, a family friend of my fiance, and two of his friends. We've told ONE member of his family about the wedding (that's a whole other can of worms that I'm not getting into). Now I have to tell my grandmother, who I have not seen in 10 years (a different story), that she is not invited to my wedding. Because my mother can't keep her mouth shut. And since my family is quite southern, it's not likely that my grandmother won't, either.
My mother has also been bulldozing me and trying to pressure me into making all sorts of decisions that I don't need to make just yet (she's going on about how I need to decide on my 'look' when I ask her opinion on my dress and other things). She's stressing me out to the point that I want to properly elope and have no family present at all. What should I do?
