Hi Ladies, (sorry its long!)
I have posted on here before about issues regarding my FMIL and it has pretty much just gotten worse lately.
so here is the DL: My FI proposed in December and we are getting married in October in Las Vegas, (we wanted a pretty small wedding with close family and friends only) the DAY that she found out that we were engaged, she threw a fit because all of his family members wouldn't be able to make it to the wedding (most of them weren't going to be invited anyway bc we aren't close with them). She has had a problem with every choice that we have made and has constantly "created" wedding-related issues. I finally gave up on her and her drama about 3 months ago and stopped speaking to her all together (I tried reasoning with her many times before I stopped talking to her, even tried to give her a mother of the groom gift and didnt get a thank you or hear a word about it from her) BTW- his family is not paying for any part of our wedding, my parents are paying for everything, even the rehearsal dinner and any showers.
So.. here is what happened that really REALLY hurt me and its something that I just don't think ill be able to get over, She is a member of a online message board that I accidentally came across on google while doing some research about Vegas destination wedding drama.. while reading this message board it occurred to me that this woman was talking about our exact situation.. turns out it was my FMIL, she had created an entire thread about me titled "bridezilla" and she didn't hold back, turns she absolutely HATES me (which pissed me off because she acts so fake towards me around her family) there was over 300 posts about me on this message board.. apparently she is praying that we do not have children because "WHEN they get a divorce I don't want to have to go through a custody battle" and she has given out my personal information to her online message board friends such as... my FB page, where I work, where i go to school, AND gave out all of my parents info too! she also gave all of our wedding details out just incase any of her online friends feel like showing up and "crashing a Vegas wedding" she also said that she is bringing a group of uninvited people (a distant group of family members) to the wedding and she "doesn't care what we have to say about it) There was SO MANY more horrible things and LIES after LIES she posted about me but this is already getting too long so Ill leave it out.
I haven't confronted her about this yet (I havent spoken to her in 3 months) and I am not really sure how to go about it, for the past 7 months she has tried to make my life a living hell, my parents are having to hire security for the wedding reception just so people cant crash it now. All of this is making me pretty upset and I feel so bad for my parents because they are so happy for us and spending a ton of money on this wedding, while his mother & father are just trying to make it a miserable experience. I don't understand why a mother would want to do this to her own son?? I think by far the most hurtful thing so far was the fact that she doesnt want me to be the mother of her son's future children, and that she doesnt believe that we will stay married.
I want to badly to just put her in her place and tell her off for all of the horrible things she has said about me.. I want myself, my future husband, and our future children to have nothing to do with this woman. but maybe I just care about what she thinks too much, its hard not to

I wish the rest of her family members knew all of the horrible things she said about myself & her son. But I feel like if I "outed" her then I would be just as low as her.
any thoughts on how to handle this situation? would it be wrong for me to bring up the posts I found to her, privacy wise? (I mean, she did post them on a public site. And I wouldn't care if she read these posts that I make about her)
sorry for the long post! thanks for reading
