Hello
@Vindepth,
I am so sorry that your wife is going through such a difficult time right now and that you are feeling so emotionally detached. I know the "feelings" aren't there, but one thing that I have come to understand is that if we follow God's directions, even if we don't have the "feelings", He will take care of us. Love is a verb, not an adjective. If we love (action) our wives, over time the feelings will come. Another thing that I have found is that the closer my wife and I are to God, the closer we are to each other, but the further we are from God, the further we are from God. Please know that I will be praying for you.
25Husbands, love your wives, just as Christ loved the church and gave himself up for her
26to make her holy, cleansing
b her by the washing with water through the word,
27and to present her to himself as a radiant church, without stain or wrinkle or any other blemish, but holy and blameless.
28In this same way, husbands ought to love their wives as their own bodies. He who loves his wife loves himself.
29After all, no one ever hated their own body, but they feed and care for their body, just as Christ does the church—
30for we are members of his body.
31“For this reason a man will leave his father and mother and be united to his wife, and the two will become one flesh.” Ephesians 5:25-30 NIV
