I want her to stay

She emailed me to tell me that I need to get someone to cover the DR exercise, as she will not around to help. She said her last day would be 29-Sept.

When I looked at the leave chart, she had booked leaves from 30-Sept to Oct prior before telling me that she is leaving. I told the PM that I will talk to her, persuade her to stay, but I think it's tough.

I really want her to stay, after 2 years working together, there's already some kind of bond between us, really don't know what it's like without her around. I really like her, I did told her before in a casual way, that I like her, but she thought I was joking. I don't think the feelings is mutual, after all, she has a BF who is working in Oz, maybe he's coming back for her soon...what should I do???
