Hi, welcome and thank you for your question. My name is ***** ***** I am glad to assist you today.
I am very sorry about your issues. Did she post the video on her FB account? Or in yor FB timeline?
Please let me know by replying to me here so that I can help you further.
I am very sorry about your issues. Unfortunately, there is no one who can prevent anyone from posting on Facebook. If she posts anything not good, your best option is to look at that post, then report it to Facebook using the built-in reporting tool. That calls the attention of Facebook and will take down the post for you.
Please follow the procedures in this link to report a post so that FB can take them down:
