Tad, And one more thing...you are not under any obligation to have lunch w/your xh and her husband. If she wants to discuss the wedding, then she should be discussing it w/your son and his new bride to be. After all, you aren't the one that is walking the bride down the aisle.
If she wants to discuss what the expenses of the wedding, again, this should be directed to your son and his new bride to be. Now, the rehearsal dinner may be another story as the Groom's family usually takes care of that...but that's a year away and doesn't need to discussed at this time.
Tad, you've got this. Please don't allow this woman to ruin your relationship w/your son or future daughter-in-law.
