My FMIL just shared with us who she hopes we invite to our wedding - her siblings and their spouses. Since my FI does not really have a relationship with a number of his cousins, and those cousins' children, we do not plan (nor are we expected) to invite them.
FMIL is concerned that one particular brother will think that the invite is for his entire family (multiple children and grandchildren) and bring the entire brood to the wedding even though FI hasn't even met most of othem. She fears that even if we just put "Mr. and Mrs. John Doe" on the invite that he won't interpret it as just the two of them being invited. Unfortunately, FMIL doesn't really have a relationship with him and doesn't feel comfortable calling to tell him this.
Any suggestions for how we could word things for them or what we could include in the invite to make sure they realize it is just for them?
