My Friend, I have been where you are now. 5 years ago I retired from the Navy, and my wife left me after 15 years of marrage she took our 3 children. If not for the fath in HIM I guess I could have fallen the other way. Please remember that God will always point us in the direction we should go. At times believe me, we wont like it but with our eyes on him we will come out for the better. The path isn't always easy. Three years ago I got custody of my kid's (now 16,15 and 14) Things have to work on HIS time, not ours. My prayers are with you and the kids. 

Father in heaven,

Thank You Lord that You have promised us abundant life and no matter what happens we hold on to that promise. Father, I pray for my brother here, only You Lord understand what he is going through. Father, I pray that you give him wisdom and grant him favour and grace in his wife's eyes that she will agree to give their marriage a chance. Father, I pray that You will send the right friends who will give her the right type of advice with regards to marriage. Father, I thank You that no matter what happens, You remain faithful to us and we can count on You.

In Jesus' Name, I pray that You grant my brother strength,
