I recently broke up with my abusive girlfriend and I finding it very hard to get over it.

So me and my now ex went on a walk and talked about everything that had happened and we both agreed that we should go our separate ways as it will be best for both of us. She was quite abusive to me mentally and emotionally and theres a part of me that's really relived but theres the part of me that misses her because when she wasnt toxic and abusive she was sweet and I feel like I'm going to miss those moments. I know shes bad for me but I still feel this way. I really want to get over her and even when I'm not thinking about her eventually my mind still ends up going back to her and how much I miss her sweetness when she was kind.
