So. The toughest question of them all. What is she going to do now?
She has a vampire probably-stalker that will be wanting her later. At least for her delicious witchy life essence, if not for - for other things. That a vampire of the male persuasion might want with a young woman. Considering the decidedly sexual direction his bite took. (She manages not to throw up again, but she does need to take a little while to sob herself calm.)
Since he isn't keeping her in a dungeon and biting her regularly to drain her lifeforce enough to keep her magic away from her, he's either not worried about her potentially surprising him with magic, or he hasn't thought through this endeavor of his. Somehow she doesn't think it's the latter. When he... had her... he definitely seemed like he knew what he was doing. She doesn't think that rules out that she could maybe out maneuver him and catch him off guard in some way, but. Well. It does mean that she's probably dealing with someone that has done this kind of thing before. And she has decidedly not done this kind of thing before. She's not going to bet on being able to beat him in a direct confrontation.
Maybe she could try running. Not back home, he would probably be able to find her parents, but - somewhere. Vampires are weakened by sunlight and according to her mother don't like going out in it, she could maybe just - get away. Sail to the mainland, or something. Get away from the vampire and make a new life elsewhere and hope he never ever comes after her ever... But he would be able to find her parents if he had motivation, and seeing as how she's a witch that knows about vampires - she had to get that information from somewhere. She very much doesn't want this person doing to her mother what he did to her. Maybe they all could run off to the mainland together, but that doesn't sound like the kind of thing that she could sneak under a vampire's nose very easily. Just by herself, she's not confident she could actually outrun a vampire that thinks she's delicious. It doesn't sound like a pleasant way to live her life. That'll be her backup, then. Try to solve the vampire problem first, then try running away.
So, without running away or fighting him, how does she solve the vampire problem?
... Uh.
She'd like to talk to him? Well, not really, she sort of wants to crawl in a hole and never ever see him again, but if she doesn't get that, then she'd like to talk to him. So she can at all know what he wants besides, demonstrably, to eat her. Once she has that, she can try to figure it out from there. So how does she get him to talk to her?
Okay. If she were a bloodthirsty creature of the night that wanted to have delicious, delicious witchblood, what would she find annoying? ... Stalking the witch containing it. That'd get really old really quickly. But he needs to stalk her, because her hours are often unpredictable, and he doesn't know when he'll have a good opening. If she - if she spares him an annoying bit about being a vampire, makes it so that he doesn't feel rushed to get right to the, the biting, then maybe he won't skip straight to that. Maybe he'll go, 'Why aren't you running away, silly witch?'
Which would be a foot in the proverbial door and maybe get her something more to work with than 'I have an all powerful vampiric stalker out to drain me of my fluids.' It's - something. She doesn't like it, but she likes it more than 'wait for him to ambush her again.' By a small margin. ... Very small.
