Don't get me wrong, I'd pick having friends over not having them, but I feel like that statistic is a sort of fear mongering tactic used to drive people to change themselves just to BE in a relationship. I've pretty much gone my whole life without having a "best friend," and yeah, it has hurt, and it definitely has led to some insecurities, but I don't think not having a best friend was necessarily the cause of whatever cognitive dissonance I live through now. I feel like more of my negative self talk and self-image came from negative experiences from past friendships, rather than being alone. Instead I feel like being alone sort of amplified the residual pain from those experiences. I dunno, I could be talking total nonsense but it just seems a bit farfetched. Dementia, probably not. Loneliness leading to insecurity seems at least somewhat more reasonable. Let me know your thoughts, because I'd much rather live on my own and have the liberty of being authentic then live in a relationship built on a fabricated foundation.
