The quote "I don't think you ever wanted to be happy anyway. It don't suit you, so you managed to avoid it." from Larry McMurtry's "Lonesome Dove" suggests that some individuals may resist happiness due to their own perceptions or beliefs about themselves. The underlying idea is that certain people can become accustomed to unhappiness, making it a familiar state that feels safer than the vulnerability that comes with joy.
This perspective raises questions about self-sabotage and the complexities of human emotions. It implies that, for some, happiness may feel unachievable or unworthy, leading them to unconsciously create barriers against it. McMurtry's character observation serves as a powerful reminder of the many reasons people might shy away from seeking fulfillment and joy in their lives.
