I don't think age is a factor here, but if you are worried about his age, then you should not continue the relationship with him. He told you he has a few things to iron out, but he didn't tell you what they were. You seem to believe that a Jamaican woman may be included in the few things. You should ask him about that. You shouldn't be guessing, just ask him and set your mind at ease.
Some men are big liars, but some men speak the truth.
This man told you that you are his ideal woman, and that he has not found any other woman in America or Jamaica like you. It is either you are going to believe him or disbelieve him. All women love to hear that they are the greatest, the sweetest, the loveliest. If a man does not know how to charm a woman, he is in bad shape. But an intelligent woman should be able to discern whether a man is honest in his compliments.
