The couple bubble is an agreement to put the relationship before anything and everything else. It means putting your partner's well-being, self-esteem and distress relief first. And it means your partner does the same for you. You both agree to do it for each other. Therefore, you say to each other, "We come first." In this way, you cement your relationship. It is like making a pact or taking a vow, or like reinforcing a vow you already took with one another.
