Awe that's kind of sort of adorable. So then would they actually live in her house instead of his?

Hmm well I mean with the first idea of her not telling him, I would imagine that he would have accidentally find out. I'm not really sure how. Maybe he came over and find her before she had time to clean up covered in blood. He would have freaked out thinking she was hurt, and then when she told him and was terrified and sobbing in fear. He just loved her enough to calm her down and not tell anyone. 

If she told him, he might have started suspecting. Imean she's always cold, doesn't have a heartbeat, and didn't want to leave the house. I figure that he would have asked her everything. Ask how she was turned, how long she had been a vampire, if blood was the reason she moved here, things like that.

Honestly I'm fine with either of those. Which would you prefer?

Haha I've done that before.
