Honestly the one only way to disconnect is to stop seeing him. Id stop these sleepovers.

Also it’s clear he is not romantically interested. Sleeping in the same bed? And he doesn’t even suggest intimacy? I’ve never met a man who didn’t want sex all the time every time, of course not with every woman, with the one he likes in that way.

So if he was romantically inclined towards you he’d absolutely suggest romance/intimacy during your weekly visits. And he either wouldn’t sleep in the same bed or he’d definitely suggest romance during those activities.

I think to protect yourself from getting your feelings hurt all you can do is to stop seeing him
