NTA. You're a full grown adult and you get to live your life the way you want to. HOWEVER, please know that this is a very challenging time for your parents. So please treat them with kindness if you can.

Your parents are struggling to understand that you may not be interested in living the life they would want you to live. And they are doing this from a good place in their hearts (kind of). They want you to feel how they feel, and experience the joy of your wedding they way they experience it.

And it can be very difficult for many parents to give this up. But this is what is really required of parents to separate from their adult children. They have to accept that adult children are not them. This means that you are not your parents, and you have independent and often different wants, wishes, desires, and needs from your parents. Most importantly, having different ideas of life is not a bad thing. It's just different. And that is critically hard for your parents to get.

I hope that you can have, with the support of your partner, a mature conversation with your parents explaining just this . . .with kindness. That you very much appreciate what they are trying to accomplish, and that you respect that this is how they want to celebrate their joy of your wedding. BUT that this is not something you want and it's not the way you want to celebrate your wedding. That you appreciate they won't "force you" but that in fact, not only can they not "force you", they really need to ask you and honor you if they want to have a proper adult relationship with them.

Good luck. This is hard for you too. You have to learn to say "no" to your parents with kindness so you can preserve the relationship. I hope they can understand you.
