Gonna be so much Tumblr butthurt.
Maybe Ramsey will give it to Sansa so good that he will become the love of her life. It worked well for Drogo, everyone seemed cool with the his relationship with Dany.
Yeah but Drogo is a manly but primitive man with muscles and mascara and he didn't know any better, and her 14 year old vajayjay taught him the error of his ways.
I mean, I get it's uncomfortable, and sad, and it doesn't fit with people who wanted Sansa to suddenly turn into a real force for good just because she finally had enough and wanted to be stronger, but in this time period, with an arranged marriage, a lot of new brides probably get their marriage consummated in a way that isn't completely consensual, and with much nicer dudes than Ramsay Bolton. You can argue whether the story had to go there(Sansa in Winterfell) but once it did this was kind of the only way it could go. After all Theon has seen and done and been put through something major would have to happen to make him snap, and just the idea of Ramsay consummating his marriage wouldn't realistically fit the bill. In the same way, Sansa agreed to marry him, she knew she would have to have sex with him, and we as the viewer know Ramsay much better than she does so we at least should know he wasn't going to be prince charming.
So yeah, I get why people are upset, but from a narrative perspective it's really the only way it works. The Boltons waiting til after the battle to make the marriage happen makes no sense when they are primarily doing it to help shore up northern support and during the battle is when they'll need it the most.
People having a hissy fit over this somehow still don't understand the show they are watching and the world it exists in. I can't wait to read how this is the worst thing that has ever happened on a show where Theon has been literally cut to bits and multiple people have been murdered horribly in all sorts of awful and often over the top ways. The first show ends with incest induced child tossing and aside from Theon watching this wasn't any worse than half the arranged marriage wedding nights you see in any number of period pieces. But because it's Sansa it's now rape-a-geddon.
