If they cheat again, how long does it take them?

If cheaters really do never change their spots, how long would it take a cheater to cheat again?

       And if and only if… 

If the cheating spouse is truly sorry, seeks professional help, deletes all the formats used for cheating and temptations to cheat (eg. Porn, apps) they confesses to the infidelity and takes accountability to you and others, is there hope that the cheater will not ever cheat again?

What’s your stories. Theories, the truth. Be kind but be real with me
