Back with my more rarijack nonsense. This time I decided to add a ship meme to make my headcanons known lol
I think Applejack would be very affectionate in most ways since she had to deal with loss very young and has learned to not take anyone for granted. Rarity doesn't mind this at all, she loves the attention.

Rarity's main love language would be gift giving, she'd make all sort of handmade things for Applejack and she would treasure every single one of them.

In my mind the got together during season 4 and are basically an established relationship for the episodes to come after.
