If it works for you, that’s great.

A friend of mine maintained a “relationship Kanban” board on his refrigerator years ago, and I believe it led to his divorce.

I personally think that using an Agile process for a relationship turns the relationship into work. Perhaps it doesn’t for you, because for you it is still fun — a kind of game.

Also, sometimes too much communication is not a good thing. It is sometimes better to listen carefully, and try to be sensitive, and infer. If you listen carefully, you don’t need to be told explicitly in a “retrospective” what it is you do that bothers someone: you can infer it, and then just stop doing it. When someone has to tell you, it establishes as a fact that you are annoying them.
