I'm so sorry that happened to you.

You can't just stop loving someone instantly. But, you have to stay safe and stay at a distance. As Stoda says, as time passes you'll disconnect from him.

There is a meditation I used to do with my religious group. I don't know if you're religious or not, but you don't need to be really. It was where you would meditate and imagine that you are connected to the people you know with a silver cord. For the people who were abusive to you, you would ask for the strength to sever that cord, and then imagine yourself cutting it with a scissors.

Unfortunately in life sometimes we have to let go of th people we love. As time goes on you will heal and you will find someone who really does love you. None of this was your fault.
