I didn't fully read the article, so maybe something I there talks about this or the ineffectiveness of this, however, what I find the most helpful is simple: tell the truth about how you are actually feeling. I think so much of burnout and resentment/cynicism in general but especially in romantic situations is paying more attention to what the other person is feeling than how we are feeling. And that in many micro conflicts, we don't say how we're feeling, such as saying yes to someone when we want to say no, agreeing when we want to disagree, and more. If you give more specifics on the situation, I'd love to give more suggestions on what has worked for me. If not, I understand and I'll stick with being more honest with myself and others about how I'm feeling has helped me a lot.
