From what I gather, you will have a long way to go -assuming everything goes well in time with the green card process and for him to bring you even after he has the card-its gonna be a long wait. My suggestion would be to -why not apply for a visa again, may be a student visa or somethingand yeah keep filling that dv form (shortest and the sweetest way IF). You being married obviosly makes it harder on you and the decision that you make now will shape your whole life. Some people above are too personal and i don't think anybody should advise you on your personal relationship based on some incomplete facts. You shouldn't be misguided by those.If you have been talking to him on  skype every weekend, you should already have pretty good understanding if he is loyal and if he is headed towards keeping his words. Before building the shadow of doubts, be optimisitc and give it a chance and try to work out things together. Tell your husband how you feel-I bet he will understand instead of listening to some random people who barely know the circumstances. I wish you luck and hope everyhing works out the best for you.
