Im a single parent, I have no financial support for either of my children from their fathers, one is a pre schooler, I got made redundant last year and after looking for work for nine months had to take a 66% pay cut in my new role. I now work part time, UC helps cover my nursery costs. I have tried to move house - sale, and therefore onward purchase, fell through. I have had a very stressful few years.
Sometimes my mum calls to tell me how much my status as a SP and home”owner” are worrying her. How it keeps her up at night worrying over me.
I almost never speak to or see my mother as a result.
She is not a victim here (and in most ways neither am I). I am making it work the best I can for now with an eye to what will benefit me and my children best in the long term. Her stress is NOT my problem to solve and I am NOT adding it to my “to do” list.
Butt out. If you care then offer her a sympathetic ear, loads of moral support and whatever help (with childcare, cups of tea, home cooked meals) you feel you can give.
Fine to set the boundary of “we won’t be able to help financially” if you feel it needs to be said. But I’m guessing you’ve already given her that message.
If you want to have a positive relationship with her and your GD don’t make your worries her problem - she has enough of her own.
