But telling someone to exit a relationship that’s great in every way otherwise is unkind and irresponsible.

Relationships are not nearly as unique as you might think. It's easy to have a relationship that's great in all of these same ways with someone who also wants to have sex with you. All good relationships are good in roughly the same ways

As people in a relationship with someone we love it’s our responsibility to try to make things work.

Nope. Good relationships don't require a lot of work. If you can't meet the relationship needs if your partner consistently and with ease, you are not the only right person for them. The idea that relationships require hard work and sacrifice is propaganda that's spread by people who are with an incompatible partner.
