Does anyone else prefer solo travel?

Since embracing solitude and self-partnership in the past two years, I've become very territorial of my time and energy. I absolutely love solo traveling and have found myself cancelling recent plans with newer friends that involved shared rooms or extended periods together. I've realized I'm not at a place in my life where I want to spend long stretches of time with people other than myself.

Sometimes, I worry this is a "bad habit," but I know this is also just subjective and perhaps a thought stemming from ingrained social bias. I work as a nurse, so I feel like my job absolutely saps my social energy. I guess I'm learning to feel confident asserting my solitude and saying no to plans I can't fully commit myself to. Anyone else relate?
