I disagree. There are clothes i used to wear infromt of my ex and I hate them now. I have peices of furniture that I've moved into a new house that he helped me assemble and it feels odd, I hate when people compliment those peicesIt doesn't shock me that she's still wearing that necklace (I personally find it weirder when people discard presents from someone when they split up - or worse: send them back to their ex!), especially since she's had it for barely 3 years and states in the video that it's a necklace she really coveted.
If she was still wearing her half of the "Till Death" Regal Rose pendant, now THAT would be odd!
Not that long ago she shot an IGTV video in her bedroom and the plush toy Mark & her had bought in Canada was sitting on the headboard, I thought that was strange, probably because it's more of an item bought together associated with memories?
