Bingo, same here.
I have an exhaustive job with quite some travelling and human contact.
The last thing after closing the door of my car in the garage after arriving at home is any other human being.
I (finally) had a week off this week and i have not left my home once. First I think it is poor management if you can not stay at home without constant grocery shopping or buying stuff for projects in progress.
I started ghosting when I gave up on dating in 2000 or so. Without wanting to meet women much of my existing social circle became kinda useless and I only stuck with some good friends of my childhood.
We help each other out if one of us has a little problem like feeding the cats when in hospital ...
I also ghost at work, my only "social event" there is the annual christmas celebration.
I do not drink at all and even that gets rather boring for me after some alcohol consumption of the others.
2017 I will be 40 and I think I will either cut back on hours (and money) or work even more and save for an earlier retirement.
