Search Results: more than friends with benefits

I have worked with this woman (28 years old, married) for a couple of years. We have always got on really well but of late seem to have become closer, emotionally. There has been nothing going on but she does say the odd thing that makes me wonder if she has another agenda. I have definitely caught her looking at me in her peripheral vision. Lately she has taken to wearing fairly low cut, tight tops to work (she has a blouse over it but it is always tied below her chest and so open at the cleavage when I see her). I don't remember her doing this in the past, except on one occasion, and now she seems to do it practically every day. She has a chest that a nineteenth century novelist might describe as 'ample' and I assumed that she dressed modestly as she was conscious of it and didn't want it to be seen. This change could just be a style thing, it is summer so maybe it is just cooler, but I'm not convinced. Yesterday she put her head round the door of my office and practically rested her breasts on the doorframe, which made them even more obvious than normal. I had to look away for fear that I would stare.

We work in a small company so one thing I am certain about is that it isn't for another man at work's benefit as I can rule them all out. I don't think she is trying to impress a female colleague either!

We share a fair amount of eye contact and sometimes it goes beyond 'normal' but I'm never really sure what it means. It does concern me that she may be doing this just to get some attention rather than because of any desire for me. Is there any way that I can tell without asking her (that would make it very difficult at work so isn't an option)?
