Disconnection is not something someone gets rid of, but more something that two people evolve past. When a couple is disconnected, they have reverted back to a state they once were, before they met. They are back in a time where they do not rely on each other emotionally. To become connected is to advance the depth and mutual relaiance in a relationship to a state of mutual reliance. The first step is to recognize that you both need and want to be together, to no longer be alone. Following that, to become connected requires a series of choices, risks, and opportunities to invite the other person into your daily life.
While grand gestures are great, emotional intimacy is more strongly built by understanding the everyday life of the other person. Sharing deeply about your day, your thoughts, your struggles, your hopes, things you find funny, things your boss told you, and things that drove you nuts that day are all ways to invite your partner into knowing the real you. Conversely, when the other person shares of themselves, listening intently and actively participating in the conversation is a way to make it clear to the other person that you care, you are a safe person to share things with, and you want to know them.
Couples become connected when they try, and they move out of their isolated comfort zone. Invite your partner to connect with you, and give them something to connect to.
