you have enough on her to show the police she's been harrassing you, and if she does it again after the police talk to her, you can get a restraining order -- and if she does it again after the restraining order is in place, she will be arrested.
"my husband has already got her with a harassment warning for pulling up drunk - at our church - and cussing him. Obviously that didn't get through to her." --
wow, that's really sad. if i were you, i'd be contacting the police right NOW, to get the ball in motion -- you may not even have to wait to get a restraining order, since she's already been warned...and then, i'd bring all her harrassment history with me to the court hearing, and hopefully get her visitation ELIMINATED -- she isn't the parent, so her rights are very shaky...they can snatch that visitation from her in a second. i wish you luck.
