I think he is too old for you. He may be a nice man but an age difference of that much means you two probably don't have very much in common. Your friends and his would be too far apart in age too. Those two factors should be taken into consideration. You also said you thought he was was way too old for you. If you go out on a date, he will get the idea that his age doesn't matter and obviously it does, not only to you but your whole family.
