my abusive ex husband is posting all kinds of lies, my new husbands ** year old mug shot, and photos of my kids, reporting that i kidnapped them, all over facebook. i was contacted by a few friends yesterday with screen shots of what he was posting but because i'm blocked, i can't see it on my own page. i have mountains of evidence of his abuse, including sexual abuse of my daughter, who he is posting pictures of (along with my other three kids). he has no evidence, whatsoever, but my husband's career is jeopardized now because his mug shot is all over the place. i have asked friends to flag and delete this post whenever they see it, but now i've had over a hundred friends unfriend me because they believed him, without evidence, over me. *i can't have him posting all these lies about me, it puts me in an unfair position, it's harming my husband's career, and my children have now seen it, and my daughter is in a full blown PTSD attack. i've had to put in emergency calls to her therapist. *i have been advised that if his facebook account is not deleted, i can sue facebook for slander. *i was going to delete my account, but was advised to keep it open until this is resolved.
