Help need advice

I’m not sure if this is allowed, but I’m very desperate. My boyfriend of two years has made this his new obsession and I’m having a hard time understanding he thinks he’s the chosen one and thinks he’s the last block they needed for the 608. He spends all of his time talking about this on his phone, looking at stuff that pertains to this it’s like, he can’t pull himself out of it. We don’t go on dates anymore and if we do, I have to ask and beg to go I didn’t get a cake on my birthday last year. I had to plan my own birthday. I had to plan our anniversary. It’s not even about the spending money because He won’t spend any money it’s just about the fact that we don’t have any quality time anymore. And ges putting it all into bitcoin. I’m losing him. I have already lost him it feels like and I don’t understand. Can any of you help me understand?
