DH has always had something of an addictive personality. He becomes passionately obsessed by things, and it completely consumes him for a short period before burning out and something else eventually taking its place.
The obsessions have often been fairly benign, but intensive in terms of both time and money as usually a lot of kit is bought as this thing is definitely going to change his life and this is what he'll be doing from now on
Off the top of my head there's been obsessions with pottery, coin collecting, rare books, cycling, climbing, butchery, photography, windsurfing, swimming and many many others.
However, his current one is cryptocurrency and NFTs, and he's gone down a complete rabbit hole which is making him unbearable. It's been ongoing for a couple of months now and I have literally heard about nothing else. Even conversations about what our kids are up to will be brought back to crypto, often by way of random tangent, and I certainly haven't had his full attention for a couple of months. He's also staying up to all hours to watch live videos on some new crypto thing in a different time zone or trying to get in on some new project, so he's also tired and vile.
Today he's in a foul mood because he's missed out on some NFT project he wanted in on and so he's stomping around like a moody teen. Don't even get me started on the money that's been sunk into to this.
I'm sure this will also burn itself out like all the other things but fucking hell, I'm fed up with the whole thing.
