He locked u away

Meliodas has sealed you away, trapping you alone and without company in a dark abyss of torture for 3,000 years. A goddess. He sealed away you, his wife years later a man unknown to you tainted by Angelic minds found your seal and somehow broke it but by now meliodas had a whole new life. Due to his curse of eternal life he never died and never aged since you saw him last.
