There are a number of obvious assessment indicators for mental health for an individual or couple. For an individual in my opinion the best indicator is the quality and quantity of sleep. For a couple its about the quality of communication. A common indicator of poor communication in the home is if people are always walking on eggshells. One doesn’t feel safe stating their opinion or the truth, fearing the reaction of the partner will be unreasonable. Anger issues often need to be addressed. An environment where everyone is walking on eggshells creates negative stress. If it is in the home, it becomes an unsafe environment rather than the sanctuary that it should be. If the home is not a sanctuary it becomes a household of anxiety and hypervigilance. If you find you are walking on eggshells action is necessary to support mental and physical health of both adults and children. Stress in the home is felt by everyone, including the young.
To be able to be safe saying the truth in a relationship trusting your partner is necessary. You have to trust that you are not going to be emotionally attacked or that the partner is going to shut down and avoid meaningful discourse. There are a lot of barriers to developing trust such as addictions, trauma, and poor coping mechanisms. It takes a lot of intention and commitment to develop trust.
