Why is a secondary left alone? Why wouldn't the two other people be taking care of the third as well as each other?
It sounds like you defer to them as a couple, as if they are in charge -- but you're in the relationship, too! Why not reach out to them? Also, are you seeing anyone else? Maybe you need to go out on some dates when they're not available.
