Fremesis 

The one person (or thing) in your life who gives you an endless supply of reasons to hate them but who you inexplicably cannot imagine life without. An even more vehement title than frenemy. Could be used to describe the relationship between Magneto and Professor X.

Hard-boiled, lonely detective: "Damn you, liquor. You've ruined my marriage and chased off everyone close to me, but you make life worth living. I love you, my fremesis."

Friemesis

frenemesister

That female at work that is sometimes friendly, sometimes your nemesis, sometimes you want to strangle in a sibling kind of way.

That damn frenemesister - yesterday she brought in brownies and today she's in my office talking about office style & credenzas - I don't know whether to strangle, hug, or defenstrate her.
