Why a person is blind to cheating
Do you know why a person is blind to their partner cheating?
Because they have so much respect for:
1. Their own body
3. Their Word, and
4. Their partners feelings
that it would never occur to them that the person they chose to be with didn't share those same values.
No one is smart to get away with cheating and lying. They are making weak choices and that just isn't smart at all.
