my cousin has stolen my entire dream wedding idea, AITAH for refusing to help her?

I have always been super into event planning. It’s been my dream since I was a kid to run my own business as a wedding planner. Over the past few years, I’ve been building a portfolio of ideas, mood boards, and mock-up plans. I even planned a couple of small events for family and friends, and everyone said I was talented.

My cousin got engaged earlier this year, and I was thrilled for her. She asked me for advice about her wedding, and I was over the moon. I spent hours helping her brainstorm, even sharing some of my most unique and creative ideas, things I’d been saving for my future career.

Fast forward a couple of weeks, and she announces her wedding plans to the family. I was excited to hear what she’d decided, but as she described it, my heart sank. It was my plan... Like, exactly. From the enchanted forest theme, to the color palette, to the quirky little personal touches I’d spent years curating it was all there. She even used one of the venue ideas I’d suggested and claimed it was her “dream location.”

I confronted her privately and asked why she hadn’t at least credited me for the concept. She brushed me off, saying, “It’s just a wedding. You should be flattered I loved your ideas so much!”

To make matters worse, she’s now asking me to help her execute the wedding. She wants me to “be her assistant” on the big day since I’m so “good at it.” I told her no. I said I felt taken advantage of and hurt that she didn’t even acknowledge my work. She called me dramatic and ungrateful, saying this washer big day and I should be happy to support her.

Now the family is weighing in. Some people think she was wrong for stealing my ideas, but others say weddings aren’t about originality and I should let it go. My cousin insists I’m being petty and ruining her special time.
