So, I will try to keep this short. My FMIL is a very trying woman, and is used to always getting her way. My fiance is an only child, so she keeps using this to try and plan the wedding. She's even tried to come on our honeymoon, that is how little she cares about boundaries.
The problem is, when they don't get their way they FREAK out. When I say yell, they actually are yelling. I cannot stand this, but I guess who can? They cannot argue in a productive matter and in their opinions it is always all or nothing. They either totally want their way, or you are dead to them.
It finally came to the end the other day when they got mad that our invitations say "Together with our parents" rather than writing each parent out. (sidenote; they were planning on helping us with the wedding, which is why I didn't just have my parents' names. Of course, they aren't now). They blame me for the wording of the invites, but they also felt the need to tell my fiance they hate everything about the wedding because "i planned it". The venue (he found it), the food (his favorite restaurant is catering), ect. It's always me. He's 100% taken my side and now they are saying they will not come to the wedding. I did finally blow up at them, because they constantly say they are done with him if he doesn't do what they want. No parent should ever say that to their child, especially over a line in an invitation. I told them that they need to apologize to him, that they were acting like teenagers, that they were ruining wedding planning, and that they were causing wedding drama that in the scheme of things does not matter. I do want to let it be known that I said all of this at the point of immense anger and they saw my wrath finally. It wasn't in a calm and collected way that I wish I would have. When everyone talks about blowing up at their future in laws, I actually did it.
Where would you go from here? We are getting married in about four months. I mean. I am guessing they will change their mind but they were even pulling the "How will it look when we don't come" line. Like, they want him to be ashamed that they don't approve of me. No matter what, they are his parents. When they aren't acting this way they are kind and loving. They flip like this, which I find unacceptable but I can't control them. Should I apologize for saying all of this (totally not sorry, but willing to keep the peace)? Let it ride out? I can already tell you they won't apologize to me for anything.
