I'd try politely telling her that I wasn't interested - in private - and mentioning that you are married and take that seriously. Then, if she doesn't take the hint, tell your wife.

By the way - if you've ignored her to date and she's still making passes, it may be because she thinks you haven't noticed. Women know that men can be obtuse sometimes. You need to leave no doubt in her mind that you're unavailable.
