Re: my fiance is cheating on me??
Strawberry, dump him, he is cheating on you. He will do it again. How can you not see that he is after your green card, he doesn't care for you. So what if your Dad and his friend won't be happy or even friendly after all this. Trust me, if you carry on with the Fraudia Guy, you will be more upset as a married woman than as an engaged woman. Your parents need to be involved now. No need to go to your little sister, let her study - go straight to your parents and tell them that you will not marry this guy. I bet you can find someone 100 times better. Think of your long term future.
And please don't be weak and keep saying that you think he will sweet talk you. Of course he will - thats his role as a cheater. He will say anything and everything to get that greencard and not get besti from his parents. They will be mad at him and maybe even you. But who cares. Cut your losses and run, there are so many decent men in the USA on H1's and on TN's and with Green cards and American citizenship - marry one of those - forget this guy... seriously woman you are making me worry :)
Take care xx
