Over the last year I've been trying to investigate that question within myself. I think a huge part of this is that we have been socially conditioned to feel this is what we need to make our lives complete. When I look at my friends in relationships and my single friends I don't see a huge discrepancy in their happiness, aside from those who choose to view themselves as lesser than due to this perceived lack. Plenty of relationships are frankly unhappy (I'd say a third at least). I think we place too much value on romantic relationships and not on connections in general. Do you believe it's mostly social conditioning and if so, has that changed your view on wanting a partner? The main part I miss is mostly physical intimacy, other than that my life is good.
