Cheaters are known to blow up the home life during a time of vulnerability for the faithful partner.
This might be during a time of financial vulnerability where you are trying to launch your career or were a stay at home parent for a long time. This might come when you are ill or even pregnant.
Cheaters often have no shame.
They betray and “kick” their spouse while they are reeling from the revelations of the infidelity. It is cruel and truly evil (see Deuteronomy 22:22).
Their actions demonstrate the type of person that they truly are. This is hard to believe for many of us as it is contrary to the person we thought that we married.
