The most frightening thing in many close relationships is never a lack of love, but rather that they start to "become deaf" to each other. One person expresses their grievances, while the other desperately tries to explain themselves; one person wants to be understood, while the other is eager to prove they are right. Because when facing someone most close to us, the brain often instinctively enters a defensive state, interpreting emotions as attacks and expressions as negations. Over time, it's not that they don't want to speak anymore, but they finally realize: no matter what they say, the other person can't truly grasp their feelings. Many relationships ultimately don't lose to conflicts, but to long-term "emotional disconnection."
