Erin, I'm sorry you had such a rough night. I think it will be beautiful walking yourself down the aisle and presenting yourself to your FI. Parents don't realize that their words are the most hurtful we can hear. After all, we've been trying to please them for our entire lives. I hope your mom is understanding and supportive. Good luck with it all.
Which reminds me, we recently got back FI's birth cert and it doesn't list his father. The resort says they will take the parents names from the birth cert, I really don't want it known that his dad isn't listed. It's hard enough to explain that even though they have been together 30 years they aren't married and have different last names.
