One lie is too many especially in male/female relationship. I'm sure You know this by now. It is sometimes difficult to understand what women is thinking. I guess she is still assessing the situation now. You may still have chance depends on how much she loves you. Leave her alone for the time being. If I were you, I will call her may be once a week just to "keep in touch".

By the way, how long have the 2 of you been together?
