I also think it goes much deeper than that. A couple can spend all kinds of time together but what their are doing during that time is what matters.
Do you esteem your spouse? This was a huge thing for me. Like I said, I love my husband, but like any other person on the planet he has some mannerisms that are completely annoying to me. For many years I tried to change him and his ways, not truly embracing him for what he really was. Once I accepted that this is what shapes him into the man he is, not only that God uses what I find quite annoying at times as a way to for him to serve the Lord.
Are you supporting your spouse? Or are you constantly trying to get your own way? God asks us as women to honor our husbands and let them lead. When I became submissive to my husband this completely changed our marriage. I'm not saying that you need to become a doormat to your spouse. That is not what God intended. You just need to let him lead. Many women find it very hard to sit back and trust that this will work but it does. The blessings that come from it are huge!
Proverbs 31 talks about a wife of noble character. It is something I am really striving for. I'm taking the literal translation from the bible however, I am going to make my house a home.
