If marital reconciliation with your former mate is possible, dating is inappropriate.
Gary Richmond says, "I have seen time after time where people found themselves involved in a relationship following a separation only to discover that finally their mate wanted to reconcile the marriage. They were then caught with the dilemma of falling out of love with the person they had become attracted to, before they could start the painful process of repairing the damage that had been done in the first relationship. It makes it twice as hard when you let people enter into your life. It adds more problems."
A person who feels the need to date for the purpose of experiencing personal healing should not be dating. A person who is fully healed and whole through Jesus Christ should face the question of dating with wisdom, looking at it from all possible angles, as well as considering where the relationship would be headed in the future.
God's first choice is that you reconcile with your former spouse if possible. Keep that in the forefront of your mind as you make decisions about dating.
"GOD, not you, made marriage. His Spirit inhabits even the smallest details of marriage. . . . So guard the spirit of marriage within you. Don't cheat on your spouse. 'I hate divorce,' says the GOD of Israel" (Malachi 2:15-16 Msg).
