Couples Therapy is different from Individual Therapy. The couples challenges wouldn't exist outside the couple. So couples counseling must include both partners. Our cultures has distorted the normal wholesome process of partnering and romantic intimacy.
In simple terms, rejection, abandonment, judgments or betrayal is always the problem; acceptance (love) is the solution. Acceptance of self precedes acceptance of your partner.
When both partners want the relationship to continue it will, when one partner is not committed to the relationship it will deteriorate.
Commitment, acceptance and unconditional love are ingredients of a successful relationship along with patience, humor, sexual attraction, compassion and respect.
To be an adult in a successful adult relationship requires effort. Partnerships demand time. Time to manage the relationship, time to experience togetherness, time to play.
Adult partnerships also require adult thinking, changing of "high school" assumptions about life and marriage, the release of false expectations, communication of emotions, sensitivity and awareness of life's rhythms, and a desire for personal growth.
Spiritually, partners come into each other's lives to continue their emotional development. It is not an accident that you are in your relationship.
The goal of Couples Therapy is to bring the couple into harmony with yourself and your partner. Harmony is the environment where love lives.
