<human>: Can you provide a brief overview of the text?

I hate expensive things, I rarely wear jewelry and I lose things all the time (currently waiting for a new bank card....) so I made it pretty clear I never want anything expensive.  
He bought me a ~£200 necklace a few years ago, which to me is an absolutely disgusting amount of money on a necklace! All mine are <£10 and I wear one maybe like 3 times a year.  
I wore it kinda on and off for a few years, then just stopped wearing it recently. I found it again wrapped around a cheap bracelet, and don't remember what happened after that.  
Basically, I lost it. He's being extremely mean and horrible to me, and when I said that "You shouldn't have bought it because you know I'm so crap at keeping things!" He absolutely hit the roof and just kept saying that I don't appreciate it/I shouldn't lose things etc etc.  
I told him pretty much straight after he bought it that it's too expensive and I don't appreciate it and I will probably lose it.  
Basically I'm just really upset he's being such an arse and I don't know what to do to rectify the situation?!
<bot>: Lost an expensive necklace, SO is being so so horrible to me over it and I just don't know how to make it better (99% sure it's gone forever)
