Feeling heard, recognized, and acknowledged is also important in relationships. And I would add feeling appreciated. When I do something nice for someone I care about, I don't expect them to reciprocate or change how they act towards me or owe me or anything. But I love it when they recognize what I did and I can see that it made them happy. It's even better when they still acknowledge and appreciate what I did a few days later.
Finally, I've always thought that mutual respect is important in relationships. Thinking about all the rest of this, I realized that if you respect someone you will recognize them, listen to them, and acknowledge them. So, to improve your relationships, make an effort to hear, recognize, acknowledge, and appreciate those around you. And if you feel that someone else doesn't hear, recognize, or acknowledge you, well, that's good to recognize. Maybe when you talk to them about why things aren't quite working in your relationship, you describe why with greater specificity.
