Am i the only one who doesn’t understand Why people get sad about not being in a romantic relationship?

This might sound harsh or insensitive, but I’ve never fully understood why some people feel devastated when they can’t find a romantic partner or someone who loves them unconditionally. I don’t know why but to me the whole concept seems a bit narcissistic.

It feels like you’d have to think incredibly highly of yourself to believe that someone who isn’t a family member or, like a lifelong friend, would love you unconditionally? I’m aromantic, but even when I’ve dated in the past, I never expected someone to view me as irreplaceable. For example, if a partner ever told me they didn’t feel the same way anymore or had fallen for someone else, I’d be like “kay, fair enough.” I’d understand because I’ve never assumed I was so unique or special that no one could ever move on from me.

What I find even more confusing is how normalized this expectation has become. Even people who are often described as "objectively unattractive" (whether that’s physical appearance or personality, though I know beauty and attractiveness are subjective) seem to think they inherently deserve unconditional love from strangers.
