DOES A 59YR OLD MAN get attracted to a MUCH YOUNGER WOMAN...please help?

I'm a 32yr old single female. I have done a bit of modelling in the past - nothing serious, didnt like the business so got out of it. Anyhow, nowadays i just keep myself really fit and i suppose i would say i 'look well through effort'. I went back to uni and achieved a first cl degree in my mid 20s. I've just moved to my home town to look after my sick mum. Basically i've taken a job here with a high profile business man and i like the job very much. Obviously alot of people come into the office and i'm actually being heavily flirted with by an exceedingly attractive, and charming very wealthy business man. He is a widower, his wife died 2 yrs ago and he has 3 kids, some my age. I've always liked older men. The thing is, he is not like guys my age and really knows how to say those special things and give special compliments. I'm very attracted but i can see one of the other girls in the office watching this very closely so i have to be discreet. Hes already told me that he would love to give me work, working closely with him in his office and has invited me to lunch on Saturday (in his house). Which i am glad of as I dont want to go out in public around this small town. Do you think a man of 59 COULD HAVE AN INTEREST in a woman TWICE AS YOUNG.
