Legal cruelty may be defined to be such conduct on the part of the husband as will endanger the life, limb, or health of the wife, or create a reasonable apprehension of bodily hurt; such acts as render cohabitation unsafe, or are likely to be attended with injury to the person or to the health of the wife. Odom v. Odom, 36 Ga. 280.
