How do you cope with knowing you will never be a first priority / "number one" as a partner to a couple with kids? Obviously I knew what I was getting into and feel happy and wholesome in this relationship with this couple but sometimes situations happen where I see how clearly he puts her first... obviously he's going to do so as a husband. I usually never feel like a "th*rd"as they both adore me. Is this just a situation where you just have to accept it and move on? Or is polyamory not right for me if I want to be #1 sometimes?

Note: he / she never make me feel less than or like I don't belong in the relationship. We try to make it as equal as possible but the hierarchy of their marriage does rear it's head sometimes unintentionally.
