You can say "*She **spurned** me*", though that's typically a very conscious, deliberate, and negative action. 

From [Collins][1], for example:

> ***spurn**: to reject (a person or thing) with contempt*

So you would **not** be uncertain if the woman *spurned* you (she would make sure of that).

For a more passive rejection, one where she simply isn't reflecting your affections, you can say "*My love went **unrequited***", though that has the drawback about taking about your *love* as the object, rather than the woman or the relationship between the man and the woman.
