“Destructive behaviors and attitudes can sometimes be difficult to describe succinctly. That’s why an emotionally destructive marriage is not usually diagnosed by looking at a single episode of sinful behavior (which we’re all capable of), but rather repetitive attitudes and behaviors that result in tearing someone down or inhibiting her growth. This behavior is usually accompanied by a lack of awareness, a lack of responsibility, and a lack of change.”
