I think men are mainly unfaithful because as they get older, they feel the urge to prove to themselves that they are still attractive. They need proof from outside the marriage. It's really sad. It's all about them. It's not about their wives at all.
My affections are easily swayed and I can be very unfaithful.
It only took one text message to change my life. That's when I discovered my loving husband had been unfaithful. His infidelities ended our marriage.
But this will not do, God will certainly punish you for stealing and for being unfaithful.
It's better to be unfaithful than faithful without wanting to be.
