Similar here. I've never had many friends, but, the older I get, the more exhausting I find human interaction (I am an #aspie), I started going on vacations of 4+ weeks on an island where I only interacted at the supermarket, because I had to, decades ago. I very deliberately do not maintain any friendships (and I'm married to a very similar mind, we live apart for years and only "visit" each other every couple of weeks). Whenever someone expresses their exasperation that I could want it that I am seriously pissed off. Just imagine that being forced to interact is as bad as being forced to be alone, ffs.
