I, too, work in a "creative" field and get a tad weary, like a lot of others, of having it so consistently be associated with homosexuals more than anything actually creative and academic.
About your boss and that "20 year" relationship, most homosexuals I've heard of and from and about maintain time-spanning habits with another primary "partner" BECAUSE they engage in multiple other relationships, both mutually and individually. They just establish property and routines shared with another compatible person but they make that possible because of the additional persons they have contact with as an acceptable practice of that primary relationship.
This article is so accurate and candid that it does define accurately just what the motivation is for homosexuals. The long/er standing relationships between two people is never similar to what you or I or other heterosexuals accept and know as "a committed relationship with the opposite sex" that continues through to and concludes through marriage for life. Homosexuals don't replicate that, they have an entirely different practice of "commitment" that they both seek and desire.
