two people one bed

I've been in an LDR for two years. I love my partner so much. And yet, going on week 4 in quarantine together all I want is my own bedroom with my own bed and my own bedding and my own clutter and my own smell. I got a taste of cohabitation and I'm afraid that I'll never be able to do it longterm, with anyone, ever. WHO CAME UP WITH SHARING A BED/BEDROOM? I DON'T WANT TO DO IT.
