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. I could only hope that this man is genuine. Talk to your relatives, especially your father, about him. They would help you to make the correct decision.
