How to move beyond conflict stalemates with your spouse

Dear Lori and Jeff,

My husband and I have been married for four years. For the first three years, we had normal ups and downs, but now we’ve gotten to the point where I think he needs to make some significant changes in how he shows up in the relationship and he says the same about me. The resentment has been growing on both sides and now neither one of us seems willing to budge enough to appease the other. How can we move forward without either of us having to feel like we’re just giving in?
