frenemy

Someone who has traits of an enemy and a friend.

Painting with a bland stroke, hardly mixing color on palette or canvas, working neatly, quickly, deftly, and a bit hygienically—like an Old World gentleman—over his “spontaneous” projects—indeed, “tickling” his way along, to borrow frenemy Picasso's devastating verb—he [Henri Matisse] seems never to be deeply involved or even slightly carried away by his work.

Another enemy / Not even a frenemy.

A fair-weather friend who is also a rival.

So, we're definitely not going to be friends with Ferguson? Maybe we can be frenemies. A love-hate relationship's the next best thing.
