Dating someone much older

I know with this topic there can be various different views. I'm currently getting to know a man who is 20 years older than me I'm 22 and he recently turned 43 in June. Surprisingly this man has never been married, engaged, or even had children. Both of my parents are hesitant because of the age difference but support me as long as he makes me happy. What are your guys opinions on dating someone and having such a vast age difference.
