Looking for a story

I'm looking for a story where Quinn and Rachel are together. Santana confesses she's in love with Rachel and Rachel starts liking her too. Quinn says that they both can have Rachel and try it for a while. It becomes too much for Quinn and she steps aside. Rachel and Santana carry on. I think that one of Rachel's dads yells at Rachel for hurting Quinn.

I can't remember if the story is finished or not. Any help would be great.
