I will be praying for you.
I also went through a dry spell, but have come out the other side because of a few things that I believe the Lord showed me.
First of all, He must be first of all. Instead of adding Him into my day, I make my day start with Him. Up early and seek His face. I start with communion and bible reading. I know that some would have problems with this but Jesus says do this as often as you do it in rememberence of Me. That is what I do. I have communion with Him. Then I have returned to praying on my knees, not sitting or standing, and without music. For a while I felt soaking in worship music brought me into His presence more, but now I see it can be an opiate at times. So I get on my knees by my bed and cry out to Him. Ever since I started doing this my communion, or fellowship with the Lord, has become increasingly wonderful. Now it seems I don't get off my knees without having wept my heart out, and come to the place of refreshing.
My relationship with Him is so much more wonderful, and my joy in daily life has returned as well. Hallelujah.
Peace to you, and joy too in the Holy Ghost brother.
Now about your wife. I learned something about how to have a right relationship with my husband. I praise him in my heart. I think on the things that I can praise him about, and they are many, and I minimize the things I don't like, in other words I forget those things. When I do that the little specks I don't like, fade into what I do like, and the specks don't seem like so much. In fact I admire him very much now. Previously I couldn't find much I liked, but that was a lie of the enemy. To bring it down to a purely visible parable. You buy and classic car and have a vision of what it will be like restored. At first it is gorgeous, then you see the flaws, the scratches, rust, worn upolstery, etc. You get discouraged, but if you can keep the vision you had in the beginning you will love that classic car.
It is when we grumble in our hearts about someone that we aren't able to love them as we should. But when we give thanks for them and focus on their good qualities we will value them as God does. He sees us as diamonds in rough, but He knows what the finished product will be. It will look just like His Son. Praise the Lord. We need to view others as we would have them view us. With all our warts, and flaws, we are accepted in the beloved. Our spouses and other people in our lives must be viewed the same way. Only the Holy Ghost can give you the ability to love unconditionally. Be filled with the Holy Spirit.
