My poor gullible wife. Best words I have.....I wouldn't trade her, and I hope she don't trade me.
Best advice I can give for lengthy marriage is think of the other person at least as much as yourself and more when possible. It's not a 50/50 proposition.......but 100/100 and sometimes its 50/100. You have to be willing to be on the short end of the giving stick from time to time. Even when you don't like each other, remember that you love each other and put in the work to help the other person like you again.
For me this passage puts it all in perspective.
22 Wives, submit to your own husbands, as to the Lord. 23 For the husband is the head of the wife even as Christ is the head of the church, his body, and is himself its Savior. 24 Now as the church submits to Christ, so also wives should submit in everything to their husbands.
25 Husbands, love your wives, as Christ loved the church and gave himself up for her, 26 that he might sanctify her, having cleansed her by the washing of water with the word, 27 so that he might present the church to himself in splendor, without spot or wrinkle or any such thing, that she might be holy and without blemish. 28 In the same way husbands should love their wives as their own bodies. He who loves his wife loves himself. 29 For no one ever hated his own flesh, but nourishes and cherishes it, just as Christ does the church, 30 because we are members of his body. 31 “Therefore a man shall leave his father and mother and hold fast to his wife, and the two shall become one flesh.” 32 This mystery is profound, and I am saying that it refers to Christ and the church. 33 However, let each one of you love his wife as himself, and let the wife see that she respects her husband.
