Can a man scoop fire into his lap
without his clothes being burned?-Proverbs 6:27, NIV
Pure Escapism
I think it is important for faithful spouses to remember that their Cheater is indulging in fantasy. Their illicit relationship is not based in substance and therefore is doomed from the start.
It is escapism.
Instead of facing their issues, Cheaters decide to engage in abusive behavior towards their faithful partner by cheating, lying, and stealing their reality. It is sick, contempt-filled behavior.
Yet they will likely find that it does not satisfy.
Bills still need to be paid. Homes still need to be cleaned. Food still needs to be prepared. And children still need care.
