I believe that you should pray for him, don't ask him any questions or look at any of his things. In fact, maybe even go as far as to ask him things like "hun, where would you like your mail?" or simple things so that he knows you are not interested in it. Is he wrong to a degree not having that openness with you? Perhaps. But we do not know his struggle. Is he wrong shutting you out and not allowing you to help him? Perhaps. But his parents divorced for a reason and he probably does not have a good model to go by. Pray, pray pray!!! In the mean time, make yourself happy. Go to women's Bible study, volunteer to help those less fortunate, Meet with friends you haven't seen in years. Go on a little road trip and Pray, pray, pray!!! It is not your job to make him happy, nor his to make you happy. That is your choice. You choose to be happy. Maybe when he sees you have moved into a different direction and he can choose to pull out of the squaller too and reach for his partner's hand, he just may. Always be kind to him though and do your best as a wife to meet his needs. He can accept or decline and you will show confidence and happiness whether or not he accepts. He may see a new light in you that he needs. Jesus will guide you and you will find your happiness in Him. Something I read and love is James 3:16-18, For where envy and selfish ambition exist, there is disorder and every kind of evil. (this would be like coveting others marriages, or any kind of sin) 17) But the wisdom from above is first pure, then peace loving, gentle, compliant, full of mercy and good fruits, without favoritism and hypocrisy. 18)And the fruit of the righteousness is sown in peace by those who make peace. I also love the verse that says Delight yourself in the Lord, and He will give you the desires of your heart. Psalm 37:4
Good luck Sister!
