Blimey you really are having a tough time of it!!! I hope you get it all sorted out soon!!! I think I would have given up by now!!! Have you tried squirting with water everytime she starts being naughty and aggressive? Dont know if it will work for you but I know that it worked for me to deter Oscar from getting overlly rough with Fifi when they were playing!!!

Hope you can get it resolved soon x x x
