You'll have a hard time believing that being alone is so much better and you'll try to look at his circumstances, if you're a person who struggles with loneliness.
Early into a particular friendship I met this couple and the guy kept joking about how I had it better being alone than him being with his girlfriend, how much it sucked and so on. But at the end of the day you see these people at times recalling why they're together and that suddenly seems like bullshit. "Being alone is amazing and what you can do alone makes you stronger" can be interpreted as pure cope coming from a person that has been either unsuccessful or has been in several relationships that aren't worth it. But it doesn't necessarily mean that.
I had a weird decade where I went from nothing to having a lot of people rely on me and be affectionate enough that it gave me this false impression that I could be appealing to any woman whatsoever. I lost most of that and when I wasn't getting any of that, I actually felt a bit better. Suddenly I need to become a different person because of circumstances around my family, some of those people come back, I meet newer people, and suddenly I'm feeling like shit again.
