Thank you for the response.
I do not know how to handle the situation. Sometimes I think I will forget all the feelings and attraction I have for this person and completely ignore it. I feel like this as although he looks at me and sometimes talk to me, I am not sure he is actually interested in getting closer to me. Then I remember that he was looking so sharply at me and also the fact that I am lonely and need to relax and have a little bit of fun in life, which I have not done for nearly 3 years in my life. So I think that I might try to get to know this person. But at the same time I do not want to be a fool and appear to needy (in case he was just looking at me). Although I know that he is not married I am not sure he is already with someone, just like he does not know anything about me. This whole thing is confusing and a bit depressing. In past I have liked a guy and did not show him that I am interested in him (because I was shy and though I must not be too forward). He misunderstood me and thought I was cold. This happened when I was 18. He immediately went out with another girl. It was a shock to me and back then I did not understand what happened.
I work with team of 25 women. Most of them like this guy (because he is a guy). So when others are around it is hard to show him that I like him. I wish I can know the reason for his staring, getting shy or getting intense around me (but like I said it could be nothing). I have known guys who like me (I did not like them) and they were quite straightforward with expressing their feelings.
Sometimes I think this person at work might just be checking me out. He might look at all the other girls too (considering the fact that he is friendly with this other cute girl who has many guy friends). So he just look at me. there are lots of attractive girls working with us, and of course there are many many girls he can date outside of work too. He really make me confused with his moods and intense looks sometimes. Other times he is shy. He does not give away anything, except the way he looks and the his nervous behavior.
I keep on thinking about the whole situation with his guy at work and I am getting a bit depressed as I do not know what is the best thing to do.
