I ended a friendship...my friend was mean, backstabbing, and 10 faced?

but I really enjoyed being around her before I found out all of that stuff. She was happy, creative, bubbly, and was a funloving person. I will forgive her, but that doesn't mean we can ever be close again. A part of me never wanst to talk to her again, but another part of me makes me miss all the good times and I wanna get her back as a friend but that's pathetic on my part..what do I do?
