Therapy with couples is provided to help with relationships.
It's not easy to make a close relationship between two people work. Whatever made you want to be together, there may be times when it doesn't seem to be the way that it was or could be. Talking with somebody else (who is not in the relationship) can help you both explore and understand what is going on.
While many benefits of individual therapy apply with couples, there are important differences. With couples, the focus is on the relationship. If you have particular issues as individuals, this is not the space to deal with those except where they directly affect the relationship — so I will direct you to alternative sources of help for these issues.
As the therapist, I am an outside observer. I can share how the relationship appears to me, and what I notice about you as individuals in the relationship. Full confidentiality applies.
There are also differences because there are two of you; for example, the sessions will be longer, and normally there will be fewer of them. Commonly there are gaps of a few weeks between sessions in which you can both continue to work together on matters that come up when with me. (I can suggest practical changes to try out.)
