My future MIL has changed her mind about coming to our wedding in October 2016 pretty much since we told her of our engagement. She's gone from being excited and wanting the plan the rehearsal dinner to saying she wasn't coming at all and not to send her an invite, all in one week! Now, the wedding is far enough away that I've just been letting her go back and forth (she recently called up my Fiance and left a vm on his phone saying she wasn't coming when he didn't call her back because he was at work) but I'm not sure when I should put my foot down and take her up on the "not coming to the wedding" threat. I've never had any real problems with her, personally, and I certainly do not want to un-invite her (she is my Fiance's mother, after all) but I also do not feel like have her threaten to not come to her son's wedding simply because she isn't getting her way for the next year.
There is also the added bonus of her having issues with both of my future Brother-in-laws, and I'm a little afraid she will end up making a scene at the wedding. both of the brothers are really great, and I'm sure if I ask they'll deal with her, but because they refuse to speak with her I'm afraid she's going to turn my wedding into a therapy session for herself. Does anyone have any advice on how to speak with her about these threats and her possible actions at the wedding?
Re: Future Mother-In-Law troubles
And whatever happens in that time, let your FI be the one to deal with it.
First, do not accept any money from your FMIL for the wedding. She will hold it over your head the entire time. You could have this crazy rollercoaster the entire time you plan your wedding, if you take her money. If you don't take any money from her, you don't have to discuss the wedding with her at all! Don't discuss it with her. If she brings up the wedding, with suggestions, just say "We haven't planned that yet, but will keep your suggestion in mind when we do." or "The wedding is so far away, we aren't even thinking about it!" Then change the subject.
If she says she isn't coming to the wedding, just say you will miss her. She is trying to be the center of attention. Don't let her be. Also, its your FI's mother, so let him deal with her as much as possible.
Do your best to keep FMIL away from FBILs. Seat them at separate tables at the reception, etc. If there is someone who FMIL tries to "impress" with her behavior, seat that person at FMIL's table. It may solve any issues you think you might have with FMIL at the wedding.
