User blog comment:Smoky000/Why Serana cannot be married/@comment-98.109.42.250-20130608173543

I personally don't want to marry Serana. She's such a developed character, why would you want her staying in your house all day, waiting for you to come home? Seems like a waste to me.

Anyway, I have a few theories as to why she wouldn't be interested in the dragonborn:

-She's a pure-blooded female vampire, you're a half blooded vampire (if you chose vampire) / vampire hunter. She had to do awful, traumatizing things to get her gift. Maybe you're just not acceptable as a mate for someone of her class.

-She's ancient! It's very possible that she's already given her hand to someone, and they have died.

-She likes her independence, and just doesn't want to be tied to you.

-She's seen first hand that strong and emotional family relationships don't last as time goes on. Maybe she values you too much to make you part of her family (friendzone more or less).
