If a person cheats on their spouse, they would probably one day cheat on the one they cheated on their spouse with!
So as much as we should not cheat on our spouses, we should never trust those who have got to us through cheating on their spouses no matter how much they promise. The same promises were made to others before us.
Never break a home to make a home as your shall be broken one day by another wanting to make it.
Be pure, be honest, be clean, be content, be responsible, be transparent and enjoy a stress free life.
