You'd still have to do laundry, clean, cook, etc, no matter what home you live in, alone or with someone else. Those are mundane chores, indeed, I get how that, in and of itself seems to lack reward.

I will say, the grass isn't always greener on the other side, but sense from your post, it doesn't sound so much like your relationship with your husband, but frustration with a 'crappy job' and the everyday things that add up to boredom.

I can't speak much, to feeling like you do about the wage differences.

Have you looked into volunteer work, or finding a hobby, something, anything, to get out of the rut, that leaves you sounding like you want to flee and leave this all behind?
