YANBU - As a single parent I find it not only insensitive but ridiculous. People have to think beyond just child care, but also income, other forms of help etc.
The worst offender in my life has a husband who is a barrister and she hasn't worked since becoming a Mum, 19 yo is at Uni and 16 yo is at college and a very sensible & independent teen who goes directly from College to specialized sport training and is gone from the house from 8-6 daily, often later, taking trains so not needing lifts etc. 16 yo also works all day Sundays from 10-6 pm. This person goes on and on about how it's so hard b/c she's like a single parent. FWIW she also has a cleaner and dog walker and as mentioned hasn't worked in 20 years. She says dh can't do anything, so it's like being a single parent, completely forgetting he brings in a six figure income, cuts the lawn every weekend, puts bins in/out, does the driving for Uni child to come home monthly for an extended weekend and various other things. Like mentioned, also brings home a six figure salary.
I also find it a bit
when friends who are divorced whose ex are involved and have the kids part of the week (obviously not all ex situations are like this) say they have no childcare or help and ex does nothing, how they never get a break from their dc, when as said their ex is involved and has the dc weekly or every other week. I have a friend who does/says this all the time, yet ex has the dc two days a week after school so she can work longer days and not have to pay for childcare. He also has them every Saturday from 12 pm to 8 pm. During this time she sees friends, has a coffee in town, reads, walks the dog, occasionally goes out to the cinema with friends, or just has the house to herself for 8 hours. I get it, during the week it feels different as he isn't there to help with morning or bedtime routine, but don't pretend your arrangement means you get no break. You do.
I think sometimes when people have it hard in one area of their life, they need to make it seem like it is all challenging. It seems easier for people to say they are like single parents, rather than say their partner isn't around 45/50 hours/week but they are grateful for good income and their being around at the weekends. Similarly, it seems easier to say someone doesn't get a break instead of I find morning/evening routines harder since the divorce because there's not another adult to help, but I really enjoy my break on Saturday because the dc are with him and I can have a bit of time to myself.
There's no award for being in the hardest situation. I also think the problem with making it seem worse than you have it, is it almost takes away from real hardships people face.
