I'm sorry that you had to experience that from my own experience, you can't just instantly not love him anymore, no matter how badly he beat you. What you can do, is recognize and decide that you deserve better, and concentrate on loving yourself, and picking up the pieces. It's not easy dealing with such a traumatic rude awakening, the shock alone takes an incredible toll on you. Trying to switch off your feelings will only hinder the natural progression of your process. Please look after yourself and take GOOD care of yourself, you're worth it. I'm just a PM away if you ever want an understanding ear
