Physical & Emotional Abuse Support Group
Abuse is a general term for the treatment of someone that causes some kind of harm (to the abused person, to the abusers themselves, or to someone else) that is unlawful or wrongful. No one deserves abuse, period. Abuse can be emotional, physical, or sexual.
You've already determined you're done with being treated that way, next steps are up to you how you proceed & feel comfortable proceeding.
I'm sorry that you were talked to like that. It's not okay.
Maybe even try saying "you know it really hurts my heart when you say things like that to me. remember when you were my safe place? please don't take that away with such hurtful words." Sounds corny typing it but if that's how you feel it may make him think. If he makes fun of you, you know where you stand with him...
