When Debbi met Steve in 2011, she believed she had found her soulmate. But her extreme jealousy soon overshadowed their romance. Diagnosed with Othello Syndrome, a psychiatric disorder causing irrational suspicions of infidelity, Debbi has gone as far as making Steve take lie detector tests when returning home—even after short errands.

Her paranoia intensified after past relationship trauma. She’s restricted Steve’s TV time, monitored his devices with filters, and even questioned his reactions to ads featuring women. Though extreme, Debbi insists these measures bring her peace of mind.
