Is his opinion correct? (Details inside)

My very young-looking, healthy cousin of 40 has met a gentleman of 53years old. Both of them had been through difficult times with previous relationships and it finally seems as though they found love, understanding and support in each other. Financially they are okay but the problem is the gentleman desperately wants a family even at this late stage. My cousin believes it’s far too late for both of them even to be thinking of such a thing. She correctly claims that the poor child will have “grandparents” instead of parents and that it just wouldn’t be fair on the child. He on the other side state that he is psychologically, financially and emotionally stable to make such a move and that it has been his life dream which for some or other reason never materialized. Just speaking about having a child makes him beam all over and brings tears to his eyes. He says that despite a few minor health problems of his, he is more than ready to face this chapter of his life and that my cousin is over-reacting especially since she is younger than he is. Well, what do you think, is this a selfish way of looking at things?????
