Marriage….. or Not Marriage?

I have been building up a relationship with a woman over the last few months, she used to sit over the other side of the room and now she sits directly behind me!

She likes to talk to me and I enjoy talking with her. When I am talking to other people at the coffee break I can feel eyes on me, I look around and Harriet quickly turns away and drops her head then looks really shy.

She is a lovely woman and I kind of get the impression that she, well, likes me.

I found out that she is getting married and thought, if you love this guy then why are you flirting like crazy with me.

So my question to you people is this:
Should someone, it doesn’t matter if they are male or female, flirt like this if they are apparently getting married?
