Here are more of the Mane 7/8 shippings I have!
 
FlutterSpike: After being heartbroken by Rarity, Spike was sitting by himself when Fluttershy decided to cheer him up by making him lunch at her cottage. After eating a bit, he started to tell Fluttershy the rocky relationship between him and Rarity. He was surprised how open he was to Fluttershy. They slowly made these lunches into a routine, followed by helping her animals to flying together to when they eventually were considered dating. He made sure she was happy and comfortable with him. He didn’t want this to end up like him and Rarity. He matured with Fluttershy and after a while, Spike finally proposed and married one another.
 
FlashLight: Being from another dimension, Flash Sentry had to learn to be a pony for a while, with Twilight being by his side. He started to train to be a guard and eventually became one of the first guards of Twilight Sparkle’s army. Not too long afterwards, though, a battle came to be and Flash left for a few months. Twilight was very worried for him but hoped for him to come back. When he eventually did, he came back a hero for saving all of his army, leaving him with major and minor injuries. He was ranked to top general, next to Shining Armor. But while he was healing, he made sure he spent his time with his Princess, catching up on lost time. They did everything together, even boring reading. He also started to write poems and songs about his experiences, which some became popular. Not long afterwards, he didn’t want to wait any longer and asked Twilight Sparkle to marry, which she excitedly said yes to. They married shortly afterwards and have been one of the most ideal couples in Equestria. They have a compassion for one another that royals should have.
 
Caramel-Apple: For all the years he volunteered helping out the farm, Applejack grew close to Caramel. She knew all his flaws and which buttons to press or not. They were like two peas in a pod, as Granny said. Applejack never realized his feelings for her after he broke it off with Sassaflash. He confessed his feelings to her at Twilight Sparkle and Flash Sentry’s wedding, which Applejack tackled Caramel in a big hug of ‘yes’. They married the next apple-bucking season.
 
I hope you like the little back stories to the shippings :) I will try to make more of these to explore their relationships  
(And yes, I made Applejack taller than Caramel; I thought it be adorable of her to tease him about it)
