I googled “companionate love” and found out that it means:  a love that lasts forever; a soul-mate type love; and finally, a love that loves well.  I see no reason why romantic love can’t also be companionate love.  Terming it “companionate” makes me think of a companion.  Who wants that?  Afterall, I can get a dog or cat if I want a companion.  When two people fall in love, the romance should always be there.  It may not jump out when the rent is late or when the toilet backs up, but it should always be there.  Love is love and should always include romance.  When the romance is gone it’s time to get out of the relationship.
