Raylan Givens -- Justified
I get it, Raylan is an extremely attractive man and woman fall for his character but after Ava, Winona, Lindsey, Sharon, Alison etc... Enough is enough; just go be with Winona because we all know she is who you are supposed to be with.
Emily Thorne aka Amanda Clarke -- Revenge
Do I really need to go into why Emily needs to stop getting into relationships? She can never truly trust anyone and constantly puts people in danger (whether she means to or not). It may be time for Em's to move to a secluded island and give up on revenge once and for all.
Tate/Kit Walker/Kyle Spencer/Jimmy Darling -- American Horror Story
Basically any character Evan Peter's plays does not need to get into a relationship. Tate from Murder House "dates" Violet and she commits suicide, Kit Walker's wife from Asylum is murdered, Kyle Spencer from Coven is stitched back together and brought back to a tragic life by two witches and Jimmy from Freak Show gets framed for murder and than his girlfriend is chopped. Watch out Tattler sisters!
Schmidt -- New Girl
We all love you Schmidt and we have come to terms with your douchebag ways, but you need to stop pining over Cece and move on with your life.
Quinn Perkins -- Scandal
Oh Quinn! Instead of falling for men who are in the business of torture and murder maybe you should instead devote a majority of your time to some intense therapy sessions.
Alex Vause -- Orange is the New Black
Instead of being completely obsessed with Piper and trying to win her trust back, it may be time for Alex to focus on herself and trying not to get herself killed.
