What do i do and how do i deal with this ex best friend....?

-My ex bff

She sh"t talked me

She claimed that I did first (never did ever! In the 10 years I've known her)

She aperrently has a flirtationship with my bf

She says I stole her bf ( after we weren't friends and they only went out for a week and she told everyone that she nvr liked him and trash talked him)*me and him have dated for almost a year

She's tried to beat me up

She turned a lot of my friends agenst me for no reason

She trash talks my bf and my friends and his friends

She leves fb statuses bashing me

She has called me pretty much anything u can think of ( sl't. H*e. Bi*ch etc)

She throws stuff at me

And hates the fact tht now I'm a cheerleader and she isn't

Trash talkes all of the cheerleaders and steriotypes us all

Is racest towrds me even though were both the same race but trash talks me because I'm greek...

Steals stuff from me when I'm not home and puts it in the middle of her yard

and she had the nerve to ask why we weren't friendsyou dont deserve to suffer like this! Im sorry you are going through this but keep your head up and just dont awknowledge her, if she keeps trying to aggravate you and fails she looks like an idiot and desperate for attention and people will see her for the person she truly is and will always support you! Find people you love and trust and surround yourself with them and just move on with your life becasue you will make something of yourself where as this girl will spend her life desperatly picking fights to get some attention! Try and talk to new people and you will find that you may find a whole new group of friends who are perfect for you and treat you like a good friend should!that sounds similar to what im in right now... i would just completely avoid her... dont make eye contact... dont text or call her... dont talk to her or say things about her on social networking sites... just kind of erase her from your life... dont let what she says bother you... who cares if your a cheerleader and she isnt... she should be congratulating you on your accomplishment! anyway, she isnt worth your time so, dont give her your time!
god this is intense.how does she get into your house??well taking it to the police will worsen the situation so y not adapt to the situation. kungfu, cautious abt ur things, patience!
leave him
don't ever talk to her!
