People act like letting intimacy die in a marriage is just a minor inconvenience. It is not. It is a slow shutdown of the whole system. Biology doesn't care about your excuses. It doesn't care about your tired schedule, your work stress, or your "I'm not in the mood" every night for six months. If you starve the connection, something will die. First, desire dies. You stop looking at each other the same way. You become roommates. You become co-parents. You become business partners managing a house. Then, the body changes. You stop touching. You stop craving. You stop feeling wanted. And when a person stops feeling wanted at home, frustration takes over. That frustration doesn't stay quiet. It turns into irritation over small things. It turns into cold replies. It turns into sleeping with your back turned. It turns into looking for warmth somewhere else, even if you don't mean to. That is why long-distance marriages or cold marriages easily crack under pressure. Not because the people are bad. Because the connection was starved for too long. You can't treat intimacy like a luxury item you only buy on holidays, birthdays, and anniversaries, and expect the engine to keep running. Intimacy is not just in the bedroom. It is the hug in the kitchen. The kiss before work. The hand on the back. The "I missed you today." The "You look good." The conversation that is not about bills and children. Marriage needs fuel. Intimacy is fuel. If you don't feed it, don't be surprised when the car stops in the middle of the road. Don't wait until you are strangers living in the same house. Fix it early. Talk about it honestly. Make time for it deliberately. Protect it like you protect your money and your children. Because a marriage without intimacy is not a marriage. It is just an arrangement waiting to expire.
