OP. as a single mum, the workload is relentless with no backup, no money for eating out or going on lovely trips. My weekdays ran as follows with no variations, no exceptions during term time.
7am - shower, dress,
7.30 - get ds up, washed, dressed, fed
8.20 - school run
8.40 - drive to work
9-5.30 - work
5.50 - collect ds from ASC
6.10 - put supper on
6.30 - help with home work
7.00 - eat, clear away & tidy kitchen
7.30 - have half hour down time with ds
8.00 - bath, story, bed
9.00 - check kit for next day for both of us, log in, do any work related essentials, life admin.
10.00 go to bed.
Weekends were food shopping, cleaning, changing beds, washing, ironing, cutting the lawn, batch cooking, basic car maintenance, ds' swimming lesson, any other shopping needed - school shoes etc. Play dates or going to the park.
For eight years, from when ds was four to when he was twelve, my social life consisted of work and an occasional phonecall to my dsis if I was feeling down. I realised I had reached a new low when I enjoyed my smear test appointment because I got to lie still for a few minutes, and have a conversation about me.
Anyone who hasn't had sole care of a child full time, while working full time as a lone parent, does not understand that there is simply no spare time for socialising. No spare money either. I couldn't afford to waste £7 on a glass of wine or £4 on a coffee, with the next installment of PGL coming up. Couldn't take a day off because I need to save annual leave for school holiday cover.
Mums don't intend to abandon you, although it must feel like that and I'm sorry you feel hurt. They are simply submerged under a tidal wave of demands from elsewhere.
