As a companion to this, my partner and I developed a rule that you can't say No to a suggestion without counter-suggesting. It prevents one person continually making suggestions and the other person rejecting everything and giving zero feedback.

e.g. (bad): "How about pizza tonight?" "I don't feel like pizza." "Ok then, burritos?" "No." "Soup?" > Frustration

vs (good): A: "How about pizza tonight?" B: "I'm not into pizza, but I could go for a burger." A: "I'm not feeling burgers, how about sushi?" > Continues until agreement
