Jesus said “Love on another....”
At the altar, most ceremonies require the parties to PROMISE to love on another.
So stop with all of this “falling out of love” or “I don’t love you anymore” nonsense. Love is an affirmative act, not a feeling or state of mind.
That's a big load of crap. Love is first, an emotion and second, an action. Without the emotion, you won't have the action.
BTW, when your spouse changes over time and becomes a person that you just can't stand being around, the love is gone. When you get treated poorly, and are not valued by your spouse for anything other than maybe your paycheck, the love you once had for your spouse will cease. Bank on it. No "action" will fix that.
Not so much anymore. "Until death do us part" has been often replaced with: "As long as our love shall last".
