Things that you should not say or discuss in couples counseling include saying things that are accusatory such as "you always" or "you never".
You should also not hide the root of the problem or problems and make any promises that you cannot keep when in couples counseling.
When in couples counseling you should also not deny any responsibility for your part in the issues with the relationship and you should not ask your therapist to keep any secrets from your partner as these things can also be detrimental to your relationship.
You should also focus on your own feelings and instead of blaming your partner, you should instead express how your partners actions make you feel.
For example, instead of saying "you always ignore me, " you should instead say, "I feel ignored and unappreciated when you do not respond to me.".
And when in couples counseling you should also refrain from any hurtful comments as accusations and insults can damage trust and hinder progress.
You should also address the core problem or problems and don't avoid or downplay any underlying issues which are causing the conflict.
You should also openly communicate the issues which is crucial for healing and growth.
When in couples counseling you should also be honest and transparent as hiding information creates suspicion and also hinders the couples counseling process.
