Loneliness goes away when we connect with each other from our hearts. Disconnection occurs anytime one partner closes his or her heart to protect or control.
When two people come together because they want to learn together, grow together, heal together, share their time and companionship, and share their love and passion, they have a good chance of creating a lasting, loving relationship.
If you want a relationship that maintains deep emotional and physical connection, a relationship where you rarely feel lonely with each other, a relationship that is always evolving and growing toward deeper intimacy, then you likely have to be willing to work at it by healing your own issues.
