I think this girl is flirting with you , and you are allowing yourself to be taken in by her remarks.Her remarks are frequently flattering to you and I would urge caution on your part. As you are her boss as well , I would be doubly cautious.If she is relating all her probs to you about other males ,what do you think she may relate about you to others.
I think this girl is playing a game , for attention or whatever, and this may cause you some problems in the end.
I do not think you are in a good situation , and would suggest that you try to be less involved with her personal problems than you are at the moment.
A bit of distance , may be just what is needed.If she is still interested in you and vice versa after a bit of space and time , then ask her out , nothing too serious and see how things go.
