Marriage issues

My husband and I have been together for about 20 years, married for 11 years of it, and kids for the past 8 years.

I’ve become the sole breadwinner over the past 10+ years and since we had kids, there’s been more and more resentment in the relationship that goes both ways.

He has a huge chip on his shoulder for being a stay-at-home dad and I resent him for for that chip.

I’m willing to work, but can’t stand his attitude about anything nowadays. Is it possible to fix so much built up resentment?
