Dear Debbie,

I'm sorry to hear that the people around you or news that you may have heard,
particularly man are being unfaithful to their loving wives. But that does not mean
all man are like that. And that does not necessary means that it will happen to you.

You said 1. If the man is predestined to betray, why would God allows the couple to get married?
But what does the Word of God says? In Matt 19:6,
So then, they are no longer two but one flesh. Therefore what God has joined together, let not man separate.”

The verse states that it is not the intention of God Himself the separation of the husband and his wife.
Therefore, a man is not predestined to betray his wife, but the Bible calls us in Colossians 3:19,
Husbands, love your wives and do not be bitter toward them.

(Note that in verse 18, it says 18 Wives, submit to your own husbands, as is fitting in the Lord.)

Yes, if the husband is notti or betrays his wife, let not the wife turn away from him. Yes, it really
hurts, but let us learn to forgive, even in that situation. No, I'm not saying this b'coz I'm a man,
but based on what is said in Matt 19:6, let us not separate it.
That does not also give the excuse to man to fool around, but
to repent of his ways, and learn to embrace his wife again.

Hope this helps
