what to do when this happens?

i have a sister-in law that is obsessing over trying to ruin my life, she is trying to split my husband and i up.. she is claiming to other people that i have been sleeping with my ex and my husband is in jail.. and she has been telling people i am stripper to make money.. she messages my 12 year old step daughter and told her in detail that she knows i am sleeping with my ex.. i am not.. she is harassing my ex and his g/f now. . she mess. them last night at 2 in the morning until this morning telling my ex's g/f to check on her b/f he was with me and she was right beside him the hole time.. she is telling people i take nude pictures to pay my bills also... i blocked her from FB months ago, she recently got on my brother in laws (her husband)FB and posted all kinds of stuff on my wall for everyone to see.. saying that my husband needs to divorce me.. she keeps driving by my house, and normally i can ignore it.. its starting to effect my life. people are showing me text messages she sends them... my husbands other brother called me recently telling me she was texting him outrageous things pretending to be me , telling him to come over to my house and screw me. that i wouldn't tell??? she did this on antoher occasion with another guy, she sent him pictures of me she stole off my FB telling him that i needed to have sex with someone because my husband is in jail... this is so un called for... you should see the conversations she has with these people claiming to be me. there is a new app.. where you can use other peoples numbers to text people, and i don't know what to do its like she is trying to ruin my image and my marriage... and i have no clue why??

what do you do when someone does this to you?
i know its harassment, but it feels to me like she is stalking me. , , , and pretending to me what in the heck?? that's a little over the top.. i talked to the cops and i got to prove it is her, so that would mean everyone that knows its her has got to prove that was her texting, i know it is she rides past my house everyday and flips me off the cops went to talk to her about that but since in the texts she doesn't say its her they cannot do anything. and she has texted me from her phone claiming to be someone my husband was messing with before he went to jail??? i want this to stop... how do i make it stop, and my ex and his g/f want it to stop too..

I am sorry, this is more than a LITTLE over the top.

I do not have any wisdom except that I do know that FB offers you tools to control who posts on your wall - so that problem should be fixable. Just read FB help.

yes I blocked her, then she got on her husbands fb and posted on my wall I now blocked him cause of her .

Have you thought about reporting her on fb? And possibly taking legal action, if such exists? I know you can get stuff like peace bonds and restraining orders. I wonder if there's anything for what she's doing to you now.

I know this is very extreme in that it would take effort, but you might want to consider a white list approach instead of your black list approach.

when you have a black list approach, you basically trust everybody except for a small number of people whom you block.

when you have a white list approach, you basically trust almost nobody except for some people whom you allow to post on your wall.

I am sure FB would support both approaches. It is just that while you are using the black list approach, you are vulnerable to her tactics. What if she opens a new FB account under a different name and posts vicious things about you AGAIN? And you will need to block her new account - and she might open yet another one?

Surely it would be a pain to have a whitelist, but at least you will get to sleep well...

does your husband have any input or can he do anything to stop her since it is his sister?

What she is doing to your 12 year old is parental alienation. Can you block her from contact and supervised communication only to your daughter?

Never mind the slander and defamation of character, and harassment do you have an attorney for a lawsuit? IP addresses, can be traced!

my step daughter she is texting her things that I did not do her to dad, she told her in explicit detail what she claims I did her to her father with another man.

she is texting my phone I am getting my number changed.

the thing that is bothering me is that she is pretending to be me, and texting others that's like some kind of identy harassment or stealing my identy.. to use others to say they want to have sex with me.. who knows how she will use that in the future.. I don't even want to know its scaring me.
