If you think you may be harassing, or you think the someone you're interested in believes you are, check it out. Lastly, you mention that the woman you are interested in could have you fired if you pursue her. You also mention that you are no longer working with that company. While I am not recommending that you pursue her in the same fashion as you have been, I feel I must make you aware that you do have some opportunity to check things out with her without the fear of being fired. If you still wish to get to know her, be up front in your communication.
Some wonderful relationships blossom out of friendship.
If you do not hear from her, she is not interested, and you will know it is time to move on.
