It's SO true!! And the second you start thinking but "John" down the street does the laundry, bathes the kids etc for HIS wife.....one day you'll hang out with "John" and see a, b & c things that he does or doesn't do that you would NOT want.....it's that old saying the grass is always greener.....but sometimes that means it's because it's fed with bullsh!t!
Hang in there......how about changing up your routine so it's something new & different?
