What kind of group is your wife active with?

Some groups that are supposed to be support groups are more of trauma and drama dumping grounds that can be unhealthy. I am wondering
If this may be contributing to how your wife is sharing things that you know never happened.

When combining alcohol addiction and a group that leans drama focused, that can become another addiction that can get very unhealthy. A person begins to tap onto whatever they can to create drama rather then focusing on building healthy outlets.
