I truly appreciate all of the replies to this post. I hesitated sharing because it is so darned disappointing that this is our family dynamic. But last night I had a nice "what is going on here?" chat with myself and decided, as Presley mentioned, that I was going to have to change *my* thinking. My response is ultimately on me. I know that my mom is coming from a place of fear - she is alone and has been alone for most of her adult life. She has a lot of casual friends who come and go, but no long term friends. Her familial relationships aren't good either. She's worried about her relationships with her children even though we see her weekly, and by the way that she expresses herself, I think that she's worried about dying as she's taken to referring to herself has a little old lady - which she is not. This is not the ideal way to get people to spend time with you, but here we are.
I asked her what she envisioned for the weekend so that I could plan things that she likes. That was like pulling teeth. She simply couldn't/wouldn't articulate it, but with quite a bit of pressing it came out and was what I expected. She wants to go for walks on the beach (lol - we'll be the group of 16 walking on the beach together) but mostly wants to spend time all together at the house. I told her that that sounded great but I was worried that there would be time spent talking about other people in the family (those she is estranged from) and politics and that I wanted to avoid that. (Gossiping is one of her favorite pastimes). So at least I could clear the air about that. She also mentioned that we could play games so I will work on that. Hilariously, she also mentioned beach volleyball - not one of us plays - but it's on her to do list. She said it would be fun for her to watch us play. What? I doubt that will happen. But if we do, it will be highly entertaining!
I am going to go, and my husband will stay home (except for the party) and I'm not going to mention it until the weekend. I will come with a box of games, a list of movies/times, and a coat since it will be in the dead of winter and we'll be on the beach. I am also going to pack is my big girl pants and a couple of bottles of wine because I am going to need those. Thanks for all of your input. You offered great suggestions and it allowed me to push the reset button in my brain about my approach to the weekend. If there are any good stories that come out of it, I will be sure to share the fun with all of you.
