One thing I learned after my divorce (and I, much like you tried everything within my power to make him stay, but cheating is where I drew the line once I found out about it.) is that even though divorce is painful and awful. Getting divorced from a person who doesn't want to be with you or no longer can live with the person he hunks you've become is a far better choice for both you and your children. It takes two people to want a reconciliation to work, and shaming or coercing him with religion is likely only going to make him resent you and the family members who are helping you to convince him to stay. Even if this works and he decides to stay, it would be short lived and miserable. If he really wants a divorce and says his mind is made up, IMO it's better to give it to him and move on with your life. I am living proof that there are better things out there for you and your children.

As much as I wanted to bend over backwards and try to save my first marriage letting him go and moving on allowed me to find a man who is willing to walk to hell and back with me and my disease and treats my son as his own. On top of that I also got to move to Sweden, which was a life long dream of mine. Life won't end if your marriage does, it will just end a chapter in your life. You're allowed to have more than one great love. Perhaps your time with your current husband is up, but there is so much out there for you to discover that can enrich and enhance your life. I learned that living in misery just to hold onto someone who doesn't want to be held onto isn't worth it. Hugs.
