This is exactly why I won't follow you on tumblr :P It's my happy place where only things I love/like happen...

I think they could evolve into being happy over time if Sansa put her wishes into perspective...Tyrion was one of the very few people who was kind and considerate to her in Kings Landing, but that's obviously very AU and I think after Joffreys wedding and everything afterwards there'd be too much bitterness on his side (maybe both sides).
But then again I also ship Sansa with Willas Tyrell (I love that guy despite him never appearing or doing anything xD)
