no contact will serve you well (it's really hard to do, but it's so worthwhile, I promise)

change the number, your email, your locks. get the RO if possible. and just go with NO CONTACT, don't feed the beast. Let it starve. Don't give it any of you, any longer. anytime you do hear from her and want to reply - reply HERE - don't give her the satisfaction of ANY reaction from you

please take care of yourself
