Signs of an unhealthy marriage often include:
Frequent arguments
Unable to communicate
One or both partners seeking intimacy with others
Violence
Gaslighting
One spouse controlling the other
Lack of trust
One person controlling the finances
Lack of intimacy
Lying
No shared interests
Drug or alcohol abuse
Some signs of an unhealthy marriage are more serious than others, and partners can attend therapy in an attempt to turn an unhealthy marriage into a healthy one. Other signs, such as violence, are a sure signal that the marriage is broken and both partners are better off going their separate ways. The goal is always to strive for a healthy marriage with good communication and trust.
