I'm a GG and completely understand both sides.
Sometimes the HIT SHITTETH THE FAN! When that happens you just need to drop any outside factors and hit the basics hard.
Once you get back to that common denominator you can reevaluate everything else.
My SO loses his job - we tighten the budget and cut out the "frills". My SO goes on a diet - I support it and carefully shop and cook. I notice my girls' grades are slipping - I don't bring my work home for a while.
Sometimes you just need to get your footing back. It sounds like everybody is making a sacrifice "for the good of the whole".
Good luck to both of you!
