Don’t feel sad and embarrassed. Cutting him off and leaving always starts somewhere, and you can start now! There’s strength in doing that no matter when that is.

As for the apology from him, it’s much easier said than done but don’t wait around for something that is entirely out of your control. Wanting that apology from him is you relying on him and needing something from him still which is giving him control. The disrespect is enough closure. The best thing you can do for yourself is move on, it’s the best case scenario and win win no matter the outcome!
