Is there a no kill animal shelter for our cat?

This is really sad, but my boyfriend and I have to get rid of our cat. She has been fixed and given her shots. She is not abused and was shown a great deal of affection. She is about a year and a half old. She has always been slightly aggressive. We found her in a tree stump abandoned by her mother, bearly alive. We bottle fed her and she grew up to be a well nourished cat. Right before she was fixed, she became aggressive and attacked me like a dog. After she was fixed, she turned on my boyfriend about a week later. We have tried feliway, and following the vet's advice. We can't afford a pat behaviorist. Her attacks are unprovoked and random. She will be sweet, then something inside her will switch and she will go nuts. We have to keep her locked in the bedroom because she is a danger to us. It's not fair to her. We just don't want to put her to sleep. We just want her to be happy. We love her very much, but we have decided that we can no longer co exist. What about friends of cats? Can they take her?
