Establish Boundaries: If they are going to be “the parents” in this new configuration, they need to learn that they don’t get to dictate your milestones.
“Hi Mom and Robert, first of all, congratulations on your news. We were certainly surprised! Regarding the wedding: Mark and I have discussed it, and we will not be canceling or changing our plans. We’ve waited three years for this day, and it’s important to us to celebrate our commitment with our friends and family as planned. We hope you can respect our decision and be there to support us as we start our lives together.”
“Mom, we’re happy you’ve found happiness with Robert. However, we were quite hurt by the suggestion that we cancel our wedding. Our relationship and our ceremony stand on their own, regardless of your new marriage. We are moving forward with our original plans and the new date we discussed. We’d love for you both to be there, but we won’t be making any changes to our timeline.”
“We’ve received your news. To be clear: our wedding is still happening on the scheduled date. We aren’t open to discussing a cancellation or a courthouse alternative. We’ll reach out in a few days once we’ve had some time to process everything.”
