Morally there is nothing wrong with a 31 year old seeing a 62 year old man unless there are ulterior motives, like wealth. Many people have successful relationships with others with a big age difference. You will, i am sure, run into alot of problems from his children and family. If this is what you want and he is good for you and vice versa then I say go for it.
I do suggest that before you get too deep into it that you 2 sit and talk about how you will handle certain situations. Children for instance. You are still in your child bearing years where he may be looking at grandchildren.
Something else, At 31 you are still active and taking part in a lot of life where as for some older men and women, they are settling in to home.
I am sure you can see that you may have issues but all relationships do.
