Both.
He was boyfriend to Captain Gabriel, then stuck by the consciousness when he became an android (or went hunting for him and agreed to serve to find out what happened to him), and when he was later resurrected.
I just always felt that level of devotion, that he would agree to serve Galactus not to save a whole planet or for power, but just to find out what had happened to Gabriel was so hopelessly romantic, even if it's never been openly referenced.
