Making it seem like everyone has a highschool sweet heart and normalising going back to an ex and going back to the person that cheated on you. Isn't a good thing and stereotyping the female bisexual community isn't right either.

Not everyone has a highschool sweat heart

And noone gets back with their ex or cheating ex. Once a cheater always a cheater and they're your ex for a reason.

And in reality the couples that were always on a pedestal aren't realistic couples, they were toxic and in reality noone would put up with it, and someone like Blaine would be in jail for s*xual assault.

St Berry made no sense at all. Jesse lied, used and threw an egg at her, plus you could see Jonathan's discomfort with playing Jesse straight and plus they didn't have any build up at all.

Finchel was toxic and horrible and Finn never once supported Rachel at all.
Klaine spent more time apart, more time cheating and more time separated than actually being together.
Quick was toxic because of Quinn. Quinn treated Puck so badly especially when she was pregnant even though all Puck was trying to do was be a good baby daddy.
Brittana is good depending on the season

If I wrote the glee couples, these would be my endgame couples:

Tike
Bram
Blaine and Elliot (as they seem really similar to each other)
Kurt and Adam
Santana and a completely different female character, like the one we see that she's talking about to Brittany when she breaks up with her through a Taylor Swift song.
Rachel would be single in the end or with Puck or Sebastian (making it Canon that Sebastian is bisexual, especially since Sebastian's sexaulity wasn't actually mentioned or confirmed to be gay in the show, and not even Grant confirmed Sebastian's sexaulity all he said was he hopes Sebastian is the heir to Sue)
Kitty and Ryder would be a ship, as they understand each other
I would actually have Quinn be with Hunter, like a flash forward and you see Quinn married to Hunter
Marley with Skylar instead of Jake.
I see Jake with either Jane or Madison from S6.
Mercedes with Wes from the Warblers.
Nick and Jeff
Thadbastian would be a ship

Shelby and Puck and Puck and Kitty would never happen.

Emma and Carl.
