Every relationship has its easy and harder aspects. We are drawn to what is familiar along with the novel, and that may include some dysfunctional parts related to our families of origin.
When a relationship becomes difficult, couples therapy can be a good place to work out any conflicts or difficulty and improve relating. I like to use parts of Harville Hendrix’s Imago Therapy, especially focusing on communication skills. So many of our interactions are based on assumptions and misunderstandings that it is beneficial to clarify as much as possible and learn how to really hear and be heard.
