Would you think this is weird

OK so I've posted before about my cousin and her apparent crush on my husband (blatant to me, no one else seems to see it except for my husband who finally conceded).

I posted last week about contemplating declining the invite to her wedding. She didn't speak to me at her kitchen tea, she only invited my sister's to go to an after party with some friends and I also found out everyone except me was invited to go dress shopping too.

I got the formal invite last night and I've been desperate for a way out of it. We've got dog issues, the venue is far away so I'm thinking we accept the invite to the ceremony, stay for pictures and then leave.

Anyway. I came to a realisation about something last night and I think it's weird but it could also be coincidence so I need you ladies to tell me if I'm reaching or if she could be living out some fantasy type thing.

At her kitchen tea, there were a few decor items that were almost exactly like what I had at my wedding. Things like:

*I had baked bride and groom cookies for favours. She had bride cookies baked for her kitchen tea.

*My centre pieces were a small vase in a bigger vase with flowers in-between the vases. In the smaller vases were white candles in blue water. At her kitchen tea, her centre pieces were vases with a white candle in blue water with white roses in the water.

*My flowers were sunflowers and daisies, and some of the daisies had been sprayed blue. I overheard her and my sisters talking at the kitchen tea about how pretty the roses are, absorbing the blue water and thus, turning blue.

Is that not odd? Or am I reaching here? I swear at her wedding I wouldn't be surprised if her songs are the same as ours at this stage.

As I'm typing this something else also is odd to me. She is a natural blonde. I have brown hair. My hair is also naturally curlier than hers (she does have curly hair but it's like, not the same type of curls). I also have permanent eyeliner and microbladed eyebrows. I just realised that over the years, she had dyed her hair brown, got her eyes done, got her eyebrows done and is curling her hair in a more similar fashion to mine (I've got more coils, hers is more wavy).

Do you think she's trying to copy me/ try be more like me thinking I'm my husband's type? Or am I reaching big time now?

No we were really close before she started acting weirdly around my husband.
