It's a way off yet, as I'm only 47. I'm single, and raise my children pretty much single-handedly. Their father is good (we are divorced), but is a Disney dad, who doesn't really get involved with the nitty-gritty of parenting. Never makes a packed lunch, never does any laundry, never did a day's homeschooling during the lockdowns, etc. His choice. He has always been very work focused and is a good provider at least.
I work 4 1/2 days a week. My job has its challenges but sometimes feels easier than home!
I am a good mum. I am kind and nurturing, and am always there to help my kids in any way I can, talk to them, support them, love them, care for them.
However I don't feel like I'm living the life I should be. I'd choose things differently in another life, and have no dependents. Sorry, I know how awful that sounds. I am worn out, resentful, lonely and fed up. I dream of living abroad by the sea on my own - cliched, or what?!
My youngest is 12 years old. I sometimes wonder when it would be decent for me to start my new life elsewhere. Maybe when she is 20? Or is that too young?
Perhaps I am looking at this fantasy life with rose-coloured specs, and that all I'd feel is purposeless and lonely! I really don't know. Maybe I should stop watching episodes of Place in the Sun 
I've never particularly relished responsibility, even though I have always done the right thing. Ex has the children every second weekend. We are civil, but not amicable enough that I could request more time. And in any case, a week off wouldn't change my view. I just want my life back, selfish as that sounds.
I love my children and would do anything for them, but can anyone else relate?
Eldest is now 20 and I feel like I've been doing this forever.
