Converting a complaint into a positive need requires a mental transformation from what is wrong with one’s partner to what one’s partner can do that would work. It may be helpful here to review my belief that within every negative feeling there is a longing, a wish, and, because of that, there is a recipe for success. It is the speaker’s job to discover that recipe. The speaker is really saying “Here’s what I feel, and here’s what I need from you.” Or, in processing a negative event that has already happened, the speaker is saying, “Here’s what I felt, and here’s what I needed from you.”  ― John M.
