Just an update.
I went in to talk to her today, as it is the first time I have seen her in a few days. However, there was a guy in the office with her. The more I come to think about it, the more it makes sense he is her boyfriend. He also works there, but doesn't have anything to do with admin side of things. I have seen him in there before, a few weeks ago but dismissed it. I saw them leaving at around 10am together and board a bus into town, as if to get breakfast/something to eat.
Here is the thing: if he is her boyfriend, why does she show interest in me?
She has shown the following IOIs:
1) Stsring at me and waiting for me to look. When I catch her, she locks eye contact with me
2) When she saw me one time her eyes light up and her eyes looked nervous/panicky on seeing me.
3) she told me I dressed well / look good in the clothes I wear / look handsome (smart)
4) When I am around now, she cannot look me in the eyes or even talk to me, unless work related.
5) She came in as I was talking to someone and looked at me, I glanced and went back to my conversation. Out the corner of my eye she looked down to me shirt and tie to my abdomen, as in checking me out. As she left, she glanced back at me.
6) She held strong and focused eye contact when speaking to me, and then looked down at my crotch.
To me she seems like a red flag written all over her.
I would appreciate peoples advice on this.
Sorry for being a pain.
