P.S. Now I'm reminded of "When All Is Said And Done," one of the best-ever ABBA songs, which is essentially about two people trying to remain friends after a divorce.

At the literal level, it's ex-wife Frida Lyngstad singing to ex-husband Benny Andersson -- but the written lyrics are "gender neutral" and "orientation neutral," and could be sung by any lover to any ex-lover.
