Run faster than Usain bolt my friend.
life is not that rosy. Words can be very rosy but real life is going to be tough. You recently went through divorce, imagine having to do so again.
He wants to marry you without meeting.
He is unemployed and has no education but is willing to get money from family for a vacation. And his family is helping him. Seems so strange. Seems like an investment in GC.
With him being of no education, life is going to be very hard for him when he comes to USA (if he ever does). This will affect relationship.
Do you understand his culture? What about his food & life style?
DR is great vacation spot. Go there with your girl friends and hang out by the beach and sip some margarita. Don't jump from one relation to another. Sometime you need time to think and understand what you want and plan your future. If you are hell bent on meeting him in DR, go ahead but don't just rush into marriage and visa process. Give plenty of time to learn about him, his culture, family. Also Casablanca is one of the toughest embassy.
Lastly as one of our Vj Member (@Boiler) says .. tell him you are in so much in love with him that you want to move to his native land so that he doesn't have to leave his family. See his reaction and how he will convince that USA is where life is.
