Perhaps 'loving to be alone' is a wrong self-representation? Perhaps try 'loving not to be alone' as a self-image for a month and see how that feels.
Certainly, I have times that I don't like being around people (when I'm trying to get work done) and times that I do (when I want to be entertained/drink/celebrate). I'd be surprised if many people don't have such a conditional response. There was a lot of promotion of introversion as a personality type within the geek community not long after social media became completely ubiquitous. I can easily see people getting tired of dealing with people on line and then not wanting to deal with people as much in person, but that doesn't seem like introversion to me, it just sounds like too much FB/Insta/Reddit.
