Do you know that love is not a feeling but a choice? It is even more than that, it is a command given to us by God to love others.
If you don't "feel" in love with your husband anymore, can I offer you a challenge to love him anyways in obedience to God? Even though you don't feel love, treat him like you love him and the feelings will most likely follow. Never base your actions upon your feelings. Base them on doing what is right in obedience to God.
We are to love God. There are no feelings involved in loving God. Sure, once in awhile you will get emotional and feel great joy in your love for God but mostly it is a commitment to love Him by obeying Him.
His greatest commandment to us is to love Him and love others. That "others" most definitely includes that husband you have promised to love and cherish until you die. So love on him. You do things God's ways and you will reap His blessings. You do things man's ways and you will reap man's blessings. God's blessings are so much more superior and lasting than man's blessings.
My little children, let us not love in word, neither in tongue; but in deed and in truth.
I John 3:18
And this is his commandment, That we should believe on the name of his Son Jesus Christ, and love one another, as he gave us commandment.
I John 3:23
Beloved, let us love one another: for love is of God; and every one that loves is born of God, and knows God.
I John 4:7
