I would say mine was 10 years ago when I found out my ex husband was a cheater and a liar.
That began several years of waiting on God and seeking Him in regards to 'What's next'?
6 years later (after several attempts to reconcile) I knew that He was releasing me from my marriage.
I had to surrender my hopes of a godly marriage, more children, and everything I believed Jesus had in store for me.
I've been divorced for 5 years now and I recognize God's protective hand and blessings in the midst of all that turmoil.
I also know that what transpired wasn't what God wanted either. The situation I was in was as heartbreaking to Him as it was to me.
He is faithful.
