I’ve just been reading a thread about the fair division of household chores vs full time/part time work for couples. I became a single parent when DC were 9 and 10. After exH left, I had 100% responsibility for 2 DC 50/52 weeks a year (he did manage to take them on holiday, but never had them overnight or for more than a few hours at a time the rest of the year), house and garden maintenance, household admin, chauffeuring DC to activities and facilitating their social life (very rural so no public transport) and a FT job. It was exhausting, but I kept going because there wasn’t another option. Mine are grown up now, but I know there are 1000s of single parents doing the same without anyone to take up the slack.
