My husband committed adultery almost four years ago. I have not yet gotten over it completely but making a daily effort towards that. But, even if I try my best, how can I trust him or how can I know he is and will always be true to me only from here on?
There really isn’t an easy answer to your question, and the truthful answer may not comfort you. There is — no way — a person will be able to know if they can truly trust their spouse after their spouse commits adultery.
The reality of your situation is that you must either choose to trust him and then walk in faith, hope and charity, or you must choose to continually live in fear should he act upon his lusts again.
The only person who knows the intents of a person heart is the Lord. If you have decided to remain with him, then it will be more beneficial for you to extend your trust versus living in fear. Fear leads a person to check every phone call, every text message, and every letter received in the mail creating an uncomfortable anxiety within our hearts. Trust, on the other hand, allows us to progress forward without fear, and hoping that our spouse is truly repentant and sincere in his efforts. We will be less concerned about where he is, and more about building our relationship with him again.
I am sorry, I know this is truly difficult, the Lord bless you in your decision.
