Funnily, all of the comments posted, even the ones that I thought were a bit simplistic, were of help in the situation.
I would like to thank the lovely ladies who did the sisterly thing in encouraging me! I cannot thank you enough. I would love to hear more about your stories, maybe you could post your experience.
I have been made fun of or " cockblocked " many times by women who DO NOT WANT an older woman to be with a younger guy. Jealousy? Envy? Bigotry? I wouldn't know why...
For the men who did reply, thank you too. It 's great to have a man's perspective, many of the things you said did not make sense to me at all, but I decided to just listen and be open to a different point of view.
I applied the pieces of advice/nuggets of wisdom I was given, in the past 2 days and used the encouragement to keep confident and show interest.
We have very little interaction at work, and can't see each other, but I felt that he passed by my desk intentionally and made the most of the interaction.
I decided to go into major: Ignore Mode, because whenever I tried to talk to him in front of others, he would be dismissive or business like. This way he had to work a bit harder at getting my attention which gave me more confidence.
As fate had it, there was a work function yesterday, I mentioned it and he asked if I was coming... then invited me when he knew I hadn't been asked to attend.
He showed up very late ,I was already having a good time, talking to a small entertaining group of male and female coworkers.
At some point he sat with young pretty girls and started to flirt. I decided to have fun, enjoy the party and ignore him completely.
He got up from the girls' pit and talked to me for about 15 minutes, we had an effortless, flirtacious,entertaining interaction.
Then he said he had to mingle and talk to his boss, a very attractive and competent woman.
I waited for about 5 minutes but when he didn't show up, ended up talking animatedly to a very nice guy that I always had a crush on, but is out of bounds because married.
I completely ignored the young man as he was passing us by to leave the party, I didn't even look up. He finally came up to say good bye.
After he left, the lovely married man said :¨"Has he asked for your phone number yet? He is a strange but nice guy.

" Apparently, some people are actually aware we have a thing for each other!
Today, I followed the advice of...wearing a skirt...I couldn't believe my ears when my interest complimented me on it!
Now, if I hadn't had feedback from someone here saying that if a guy digs you he will compliment you on your clothing...I wouldn't have felt I was making progress.
So there we are.
It's quite nice to feel like a woman again. This man has a very old fashion, gallant way about him.
He knows how to treat a woman and doesn't have the desperation of wanting to be hip, or I suspect, wanting to be anything but himself, which is something I really appreciate.
Of course, he probably thinks I am much younger than I am and am not sure it will go anywhere, especially when he knows how old I am.
In any case, it is some sort of Spring enchantment and great boost to my confidence, so I am grateful.
Let's not play the Simon and Garfunkel soundtrack yet!
