They're not-girlfriends.

They fuck, they fight, and they kiss and make up.

On occasion they'll go out to dinner.

But it is not a date.

She'd fuck anything with a heartbeat.

She hasn't fucked anything since her.

They are complicated at the best, completely down right dysfunctional at their worst.

Maybe it isn't healthy or right or normal.

But it's just how they are and nobody has the heart to tell them otherwise.
