Dear Hurting, we often go through these kinds of troubles, so we may draw closer to God. I know the pain you're feeling inside very well, losing someone you love with all your heart and soul is not easy. Take heart, have faith that God will hear your prayer and will make the situation better. God doesn't allow divorce, so He will heal your relationship with the man you love, just pray harder, push (pray until something happens)....we are all sinners, no one is perfect. God would never expect you to be, but when you confess your sins to Him, be truthful and honest, pray... you will see the amazing things He can do for you.
I pray that your marriage is restored, that God knits your hearts together forever, erase all pain, hurts, mistakes, rejection, resentment, that you are both given new hearts and God's will be done in your household, that your kids' hearts are healed, and you become a happy anointed, blessed family, in Jesus' name, amen!
