Nah, don't jump ship. Just be yourself, seduce her, and have lots of fun. If you know her well already, next time she starts talking about it, tell her you have Aspergers. Do NOT make a comment on how her views are wrong, or how it's not a disease, etc. When you attempt to tell people blatantly, they just put up walls to ignore what you say. She'll come to question her perceptions through due course after getting to know you anyway. Probably, she'll just be curious and it'll become a conversation topic for a short while. Just don't let it put you off from being your charming self. It's not a big deal.
