I have been exactly where you are. First of all if he is serious about your relationship he MUST cut all ties with the other woman. Block her number and make it clear he is done with her and working on your relationship. If he wont do this he isnt being honest with you. This marriage website site helped me tremendously... https://www.rejoiceministries.org/. pray, pray, and then oray some more. God Bless you both.
