The simplest explanation I can think of is two people who are married and committed to their life together, but their relationship is more of a friendship than a romance. Typically, there is no sexual component or romantic feelings, but there is still a form of love.
Marriage doesn't always have to mean legal marriage. You could have a ceremony and commit to one another, without getting a license and all that. Technically (legally) it's not "marriage" but really, that's just a legal contract that's pretty much irrelevant these days, divorce rates being what they are.
