I am a young female need an advice.Attention males- those who are in theirs 50-60, with a good career,married for 30 years, having grown up kids.

Ok guys, all I need is an honest opinion from above mentioned group of males- those who are in theirs 50-60.
I am in my early 30, happily married for 10 years, we have two wonderful kids, my husband is very successful, good looking, fit, smart, everything a woman could ever look for in a guy.
So,long story short, I started my new job at this new office a month ago and developed this huge crush on my boss. I consider myself very professional and etc., never in million years I would think that I find myself in a position like this, but I just can't help it... The moment I saw him, that very first day on interview, I liked him and saw that he likes me a lot too. I love talking to him, we work very close together and talk a lot, but emotional bond we developed is not the concern here... I feel his energy, I feel this crazy attraction to him, like a magnet, it is sexual, I am positive he feels the same, it's so obvious, he looks at me when I am unaware and I caught him a couple of times and I know what those looks represent. I physically feel his attraction to me and it makes me feel all those butterflies inside, sitting across him, looking at him, btw he always makes eye contact which I usually can not hold for more than a few seconds- I am so confused and suddenly shy in those moments.... So I hope you got an idea. ...
Now, he is not at all the type of men I would normally get attracted to( my own husband is that gorgeous sexy type), my boss is 20 years older, he looks his age, although he is fit, which makes him look a little bit better than others of his age I guess. I have met his wife and his kids, absolutely lovely family, I feel so bad for having those wild thoughts about their father:).
I do not know what to do now, I am so attracted to him I even consider cheating on my husband just to get it out of my system and hopefully after that I will be able to continue working?but I am not even sure if he would consider an affair with me, after all he has been with his wife for 30 years and probably will not want to hurt his wife's feelings?
I just want to know, what do you guys feel, think and do when you have a situation like this- young attractive( he calls me gorgeous ) female finding you desireble, is there any hope he will pursue me or is it going to stay the way it is now- flirting, compliments, talking and giving me those looks..????
