This is one of the common arguments that show the people who tell me I'm wrong to claim there is no problem with being single, and it is demonstrably wrong so, no, I won't stop with the “you can be happy single” thing. Where in my post did I say I was lonely? Not having a relationship partner does not imply being lonely: I spend plenty of time with friends, family, and other people in my hobbies. Being single does not necessarily correlate with being lonely, in fact loneliness is a common problem for people in bad relationships. So while some single people are undoubtably lonely and many people who describe themselves as lonely are single, there is a huge pile of nuance between the two concepts.
