CHANGE THE LOCKS...as a cop and a women I can testify....THE LADIES IS CRAZIES!!! They can be like Astipsia...just when you think they're gone and your free and clear...WHAM...they're back with a vengence. I've known many a guy saying SHE doesn't have a key, only to come home to a trashed house...any ACE hardware store will make one...if you're a home owner check in a round about way to see how you're covered with insurance and make sure no mail came to the house addressed to her...in Illinois that constitutes residence...I'm not being an alarmist, but an ounce of prevention....If things really get bad, go to court and get an order of protection...Good luck...
