How Long Does the Spark Last in Marriage? If It Fades, How Do You Reignite It?

When do couples usually lose the spark? I know it isn’t a surprise, and I believe it's normal after being together for a long time. Life moves on, and comfort settles in, which means things may not be the same as in the early days.

My husband and I have been married for 3 years and have known each other for 7 years. We don’t have children yet fyi, and Alhamdulilah, it still feels like nothing has changed. I had a friend who made comments early on, saying that even during the honeymoon, we would argue and kept asking if we argue a lot. Alhamdulilah, there hasn’t been anything major so far, and we always work through things. She then said, "Wait until you have children; for now, it’s all sunshine." People often think we’re still dating, rather than being married. We’re still affectionate with each other.

I wonder, could it be because we don’t have children yet? In Islam, the love and affection between spouses is a source of barakah i believe, so I wonder, do couples with children find it harder to maintain that spark, or is it just a natural part of life? Also, how can we, as Muslims, ensure that we keep the spark alive and maintain the love in our marriage through the years? What are the steps we can take to ensure our bond remains strong, even when life gets busy?
