Taking your most recent fight to your couple therapist is probably one of the least likely ways to get much of anything from couple therapy. The therapist is not there to be a judge and decide who is right in your struggles. The therapist is there to teach you new skills so you can both get the relationship you want.
You need to set goals for what you want your relationship to be and learn the skills to get it there. So many people come in to a couple session and want the therapist to “fix” their partner. In fact, you need to look at what needs changing in yourself, and if both partners will do this, real growth and change can occur. You need to be willing to look at yourself and what you learned about relationships and love from your family of origin and see how that is getting in your way in your current love relationship. All of this takes time, dedication, a willingness to take risks, and often, frankly, a touch of humility.
If you are up for all of this, you could really improve your relationship. There are very specific skills involved in improving an intimate relationship, and for some people they aren’t easy to learn. You will grow personally in couple therapy much as you would if you were in individual therapy. If you are interested in how you contribute to the struggles you have with your partner, you could gain a lot and grow a lot and have a much more loving , close and satisfying relationship – through couple therapy.
