And I just want to point out that my abuser used allegations of abuse to cement his control over me and to isolate me from people who had been my friends.

I believe very very deeply in listening to and believing survivors, but abusers will use any tool available to isolate and discredit their victims and this means that allowing rumour-mongering to cut people off from others allows abusers even greater power, and I cannot condone that.  Due process is the only way to prevent practices intended to protect victims from being used as a weapon against them.
