Could you date a vampire?

So if you were a human and your love was a vampire could you make it work? I mean even just the blood. Most vampires need blood more often then you can give it. Which means that they will have to get it from someone else. Is your ego strong enough to handle that? Mine isn't. I would be like you've gone to that girl more then once. Do you like her? Maybe if you could make it a thing like a threesome you could make it work out. But if you're doing everything long distance well he'd really be all over the chicks. Or she's be all over the dudes. What would you do then? I'm definitely to insecure for that sort of thing.
