This lady at my work has been flirting with me for a while. Yesterday I got given my notice and told I could leave immediately. I sent an email round saying goodbye with my personal email on it so the lady has my details.

I asked the lady for coffee sometime and she said yes. Then she said she would email me her mobile number (I didnt ask for it). She has not sent it through so far.

Does this suggest she is not interested? Why did she say she would send it and then doesn't? What should I do next? Should I email her in a few days?

First of all, do NOT get hung up on this girl. If she doesn't end up sending you her mobile number, it's her loss, not yours.

Secondly, there is no way to tell if she is interested in you or just being polite based on what you said. Has there been any flirting/touching/chemistry between the two of you? Has she been giving you IOIs?

You can try to email her in a few days if that will help set your mind at ease, but don't take it too hard if you don't hear back. She just missed out on an excellent opportunity, that's all. Feel sorry for her and move on.

-That's my two cents...

The woman has been doing the following things;

She always looks and smiles at me when passing
She never talks to me when other people are around but whens it the two of us she very nice to me
The day before I left she was in the kitchen with me and I noticed she kept licking her lips (5 or 6 times) and also playing with her hair, her eyes were dilated too.
She also stuck around clearly wanting to chat

When I asked her for coffee I didnt ask her for a number - it was her that said "I'll email you my mobile number" I would have simply accepted her saying "Yes drop me a line when you are next around".

Should I pursue it by sending one email in a few days or just walk away?
