What if she'd asked you not to move away? I think you're overreacting -your mother -don't know her story at all just the facts that she is now an empty nester and has the flexibility to move. Good for her!! I'm 57, our son is 15 and for the first time ever I'm not joining them on a family vacation -to Disney! -yes I checked in with my son earlier this week about my plans after all not to go. He was good with it -taken him there twice -and the last time I was solo with him one of the days two weeks before the world locked down in 2020. I desperately needed me time. I don't do rides and I wasn't going to spend $$$ to get into the parks. Plus I wasn't going to do any resort related services.
So it ended up not making sense and my husband was fine with it. So much less packing and organizing and prepping for me too - a dream.
But certain of my mom friends were judgey - I'm not doing "family time" -how many vacations till he goes to college (we're going away next month -tagging along on a business trip) - etc. Moms get judged like this all the time -how dare we want me time, space, able to make a "selfish" decision that doesn't involve caretaking in a situation where the child is fine as you are - you don't even live there. Please try to see this from her perspective. I wrote about me because yes my decision is shorter term but "radical" given the stereotypical silly notion of Mom having to sacrifice -what do they call it these days - "self care" for their kids.
