I've went through similar as yours. My wife left me for another man. We were fighting inside and outside of the court over the custody of our son and many other things. I turned to God and asked for help. I prayed and studied the Bible every day. Nine months later, she returned to me. I asked her why she came back to me. She said she felt an incredible feelings in her heart for me, it was like all of sudden. God must have done that to her.

Anyway, I'd recommend you to read the books written by Erin Thiele "A Wise Woman" and "God Will Restore Your Marriage" (I have read "A Wise Man" numerous of times).

Keep in mind, with God all things are POSSIBLE!!!
