If you are sure she is the one that you want to spend the end of your life with, you should tell her. Let her to make a decision. Tell her you cannot just continue your relationship like this. If she really want to be with you, she has to divorce. According to you description, I don't think there is anything held her because of you. It appears to me the only obstacle is the marriage between her and her hu*****and. Tell her she won't be happy if her life is go on like that. Give her sometime to make a decision.
It is not easy to find the true love. Sometimes love is very complicated. But once you make your decision, you should always hang on to it. Wish you best!
