when you say old man, how old is he? and how old are you?
My advice is that if you feel that his deen is good you should do istikhara.
However if you conclude that you do not want to marry him at all then by shariah you cannot be forced into it. But this will bring a lot of issues up that you may want to discuss so i recommend that you keep this thread updated and our experienced bro/sisters and ulama will help you out.
