DH and I got married 4 years ago on a beach abroad. It was only us and a couple of close family members. SIL is now planning her own wedding and wants to get married on the same beach, have a similar style wedding cake and is wanting to order the same bloody flowers I had 4 years ago. I am livid! It was our wedding and she's basically doing everything we did all over again. I know in the scheme of things this is a bit petty but AIBU to ask her to consider at least a different beach?! She's an intelllegent, creative woman so no idea why she can't come up with her own ideas.
