Our most intimate relationships are the sites for our biggest joys and most complicated struggles. Every couple needs support at one time or another be it in the wake of an infidelity, the birth of a child, ongoing arguments, or in preparation for the next step of moving in together, getting married, having a child, or separating.
People do not enter into relationship as blank slates. We all have emotional patterns and after the glow of falling in love transitions to something longer term, our patterns emerge. Part of the comfort and joy of intimacy is the comfort of knowing your partner, but habits can also be irritating or even damaging. Having the courage to pay attention to what comes up for you when times get tough and make changes to make things better for the person you love is key to keeping a fulfilled relationship.
Once you've identified what is going on for you within the relationship, you're halfway there. The other key part of couples work is being able to communicate your experience effectively, with honesty and compassion. This again takes bravery, as well as a willingness to hear the same from your partner without defensiveness. Therapy is a place to practice this process until it is natural at home.
