Some long relationships become beautifully close and sexually distant.
You trust each other.
You know each other's families.
You share a home, memories and private language.
The person feels like family.
That description can be affectionate.
It can also be the sentence someone uses when they no longer feel like lovers.
Companionship is not failure
Do not insult what you have built.
Companionship is one of the great strengths of long-term love.
