I dated a Rainbow Dash.
>no you didn't
I did, for over a year. It was the happiest relationship I was in. She was okay with me being just like (You), in fact. We ended breaking up not because of how she felt about me, but because of how she felt about her friends and family. Even if your real-life Dashie accepts you, her friends and family will do everything they can to get you away from her. They will be scared that you're going to hurt her or keep her from her full potential. They will constantly put you down in private until giving her an ultimatum, them or (You), and she'll have to choose her friends and family every time.

Dashie appreciates and values you for who you are. It's those fucking other assholes in her life that you aren't good enough for. So, keep loving your waifu. She's true blue, the real thing, the cat's pajamas.
