You're in a loveless marriage. You and your spouse are constantly fighting. The only reason you're married is because you have a child together.
That child gets older and has its own set of problems. Serious problems.
Your life is miserable. You should be retiring, and instead you continue to work and stay in the schitty marriage because you think it's the right thing to do for your kid.
WDWWT? There's really no good resolution.
