Admittedly I haven't been in the GoT fandom very long (got the book series for X-mas, finished 'em, still haven't gotten 'round to watching season 3) but after the wedding and the shitstorm that was the end of ASoS I both felt overwhelmingly horrible for Sansa and Tyrion and wished their relationship had played out better for the both of them. Since then I kind of shipped it passively, but then I found your blog and feels are hitting like a wall of bricks (or ice, as would be more appropriate)
Ahahahaha yes, wanting better for Sansa and Tyrion is really, really painful because it's like, you can just imagine all the ways things could have worked out differently for them had circumstances been anything other than what they were! I'm so big on the arranged marriage trope - and Sansa and Tyrion literally have an arranged marriage!
Except absolutely nothing good has come of it thusfar and they both have suffered so much and are due so much happiness and they could give it to each other if only.
And I guess it's that if only that keeps me going, you know? Because we haven't reached the end for Sansa and Tyrion yet - they're both still alive, much to the dismay of all the people who would see them defeated and dead, and as long as they're alive, there's still hope.
Especially when it comes to these two.
