So my fiance and I have been engaged for about 9 months and our wedding is just 4 months away.  From day one my FMIL made it clear she will not be helping with a cent of our wedding and that her new husband would be footing the bill for our rehearsal dinner.  We are fine that she is not helping with the wedding because she has never really been there for my fiance and they are not overly close.  I have always gotten along w/her for the most part besides her negativity and jealousy toward her son's success.  Fiance has a huge family most of whom he does not keep in touch with so because my parents are paying for the entire wedding he chose to only invite those who he is close with, and his mother was okay with it.  Now all of a sudden she wants us to send invites to EVERYONE in her family and will not let up.  She claims those people will not come, however, we do not feel that we should have to pay for invites, and that it is not right to send invitations to peopel who are not invited.  All of a sudden she is going off a rocker crying saying how it is unfair that she has no say in our wedding, when she isn't paying!  She also went off saying that she thinks it was rude of me not to call her when my mother got her dress to tell her what it looks like....I was rushed to the hospital 5 days after my mom bought her dress, the last thing I was thinking of doing was calling my FMIL. My fiance is so upset and we don't know what to do.  We don't want to invite his family members we don't know and also we don't want to get stuck having to make my parents pay for more guests  We just don't know how to handle her and all that ends up happening when we try ot discuss it is her acting like a victim and turning things around on my fiance.  Sorry if this is long!
