Never Badmouth Your Spouse to Family

Once you have bad mouthed your spouse to family the perception one's family has is forever tainted. 

You may get angry with your spouse and decide to vent to family members. 

This is is a big mistake. Family blood is thicker than water. One's family will always take your side against the badmouthed spouse.
Then you have then created a monster.

Tell a trusted therapist your disappointments, frustrations and aggravations about your spouse. Therapists are trained to be objective. Family members are not objective.

Family members are emotionally involved and therefore have difficulty forgiving and forgetting. 

Seek  an objective counselor or psychotherapist and you will be happy that you pursued this route.
