You and the father of your children are in a heated argument. Your husband/SO is a calm person, is a GREAT father and partner,-and you have been together for YEARS. He has never hit you before until one day he snaps and hits you once.
He is instantly sorry. He begs for your forgiveness and wishes he had never hit you and promises he won't ever do again.
Do you give him a second chance? Or call it quits?
