The original question was "do you sometimes feel like a single parent, even though you're not" not "do you suffer the same financial hardship as a single parent"
As I posted before, I have been a single parent before, and yes, it was harder financially, but sometimes I feel that life was a lot less complicated and lot less stressful when it was just me and the kids. BUT...it is nice to be able to hand the baby over to a partner at the end of the day and grab that shower that you haven't managed to have for two days, LOL.
