Ah mine are little as well.
You just want them close don't you...Maternal instinct I think.
I think these days honestly 40s isn't over-the-hill like it once seemed (or maybe that's just because now I'm there it doesn't seem as old?!)
I'm used to being alone too, or at least doing the Whole Thing alone- but with someone making me feel worthless but letting me carry the responsibility for everything somehow at the same time.
Its been 12 years here, so for you, a few decades in, you might need a little time to find out who you actually are, I feel bits of my old self coming back to life, as though I've been in hibernation, but maybe for you, you might need to spend some time getting to know yourself
I had forgotten how I used to dress, foods I used to like, music I used to listen to, movies I used to enjoy....so much. That's not being a mummy, that's trying to please someone else, 24hrs a day, 7 days a week for over a decade.
