In your state (Indiana), you can get a divorce based on an "irretrievable breakdown of marriage," or that you and your spouse simply do not and cannot get along any more. A significant difference over how to spend money and/or about frequenting strippers certainly could be the basis for such an irretrievable breakdown, so based on what you write, you could file for divorce. Assuming that he is not willing to agree to a divorce, this would be a contested divorce--if at all possible, it would be beneficial for you to have an attorney help you, but you are legally allowed to file the legal action on your own if you cannot afford a lawyer (you can even apply for a break on the filing fees if you don't have the money for them). You can get instructions and possibly sample/template forms from family/divorce court.
