First, sorry to hear such a sad story... I am going to make a fairly safe guess that you have family and friends there to help and support you emotionally... Now consider what happens if you come to the USA and marry this man, when he cheats again, and he most likely will, You will have put yourself in very bad spot... Just saying, don't let your emotions over rule your brain, you know what is right even tho it hurts now, later you will be much happier.
