Jealousy has no cure

Curiosity is always at fault ; here it is baleful. It is madness to want to find out about an ill for which there is no treatment except one which makes it worse and exacerbates it; one the shame of which is spread abroad and augmented chiefly by our jealousy; one which to avenge means hurting our children rather than curing ourselves. You wither and die while hunting for such hidden truth. How wretched are those husbands in my days who manage to find out!
