I agree that being open about our interest and interaction with other people is the best defense against being unfaithful and betraying our spouse's trust.
Jesus criticized overeaters, condemned the love of money and advised us not to become caught up in the worries and cares of this world.
He emphasized our need to love, even our enemies.
Learning to love is our priority. Having a best friend who helps me learn what is seldom taught or practiced is like living with an angel.
I'm very fortunate. Sounds like you are, too.
