I would say he has something wrong mentally, he lives in the past and cannot get past what has been done to him, and I can tell you from experience, this isn't going to change. You broke his trust by adding Darryl and if you continue the relationship that will be constantly brought up, he will always say GO BE WITH DARRYL.. I say get out before u get too many feelings. Verbal abuse is the first step to physical abuse. He's already "being mean" and you are not officially together. Plus he talks to your sister to get under your skin.
