It is unclear whether the divorce will be final by the date we are supposed to get married.
That is nuts. Do you mean your fiancee doesn't know or you don't know when the divorce will be final? If your fiancee doesn't know and didn't tell you and in fact picked a date that might make your marriage ILLEGAL, then that's definitely a deal breaker.
Even if she does know and it should be fine but you are the one who doesn't know about the date situation, it is still very bad. This type of lying indicates something about her personality, and it's not good. She's either a coward, a manipulator, or basically incompetent at relationships.
