Female friend just got out of a relationship...

Hello everyone, I am sorry to be asking for advice on my first post but I honestly don't know what to do any more. I would appreciate any advice thank you so much ....

I have known this female co-worker of mine for like 2years now, she is like 10 years young then me, but we have always got on quite well, we hug each other everyday and sometimes have a little clean flirting even tho she was in a long time relationship with someone else and it was working ok.
However she broke up with her bf recently, since then she has either come to me about how much she miss him or how other guys have asked her out, in fact just now, she rang me to said she just saw her first bf (who currenly have a GF) but they made out because she sort of have feeling for him...
I do admit I am attracted to her which is why I guess I am bit jealous when she tells me these things but logic also tells me she hinted she won't go out with me... what the best thing for me to do? as a friend, I guess I should just listen and offer comfort, but as a man, I am felling jealous and my heart is hurting.....

thank you for reading......

Don't mix work with pleasure.
