Needy/occ HG?

I believe Hermione married Snape for protection, i believe it was ordered by Dumbledore and her parents were all for it, he was furious & mean, she was occ, very needy, (I think that's why I stopped reading it) I think she had to live with him in dungeons, last thing I remember is them having rough sex, he thought she was crying, but she said could they do that again?
