Love Shouldn't Cause Pain?

Trigger warning this story is pretty dark. Contains adult themes such as abuse & mention of rape.

I do not own any DC characters in this story trust me I wish i did.

Okay so here is a run down on nicknames and relationships for people who don't know DC that well
Harley Quinn (Harleen Quinzel) Is in a relationship with The Joker. Harley calls The Joker, Puddin and Mr J. The Joker calls Harley his Harley girl or just Harley.
Poison Ivy (Pamela Isley) is one of Harleys best friends. She refers to Harley as Harl or simply Harley. Harley call Ivy Red, Ivy, Pam or Pammy.
Catwoman (Selina Kyle) is in a relationship with Batman (Bruce Wayne) and is one of Harleys other best friends. She simply calls Harley, Harley and Harley calls her Kitty.

Harley slips up again resulting in Joker taking it to far, Harley turns to her dearest friend Poison Ivy.

Will Ivy tell Harley how she really feels about her... Will Harley except her or will the news send her back to the Joker?!
