I was never the 'One'

I was never the One in anyone's life. I feel like I have always been the backup person in everyone's life. Neither prioritized nor valued. I have starved for love for now like two decades and yet never found the One. I have always been used as an example or inspiration for what love should look like but was never selected. I cared for people too soon but never received the same effort. I looked at them with eyes filled with love but they only saw me as a spare key to their happiness. I have always been a substitute. The kind of substitute they use when their favorite individual isn't paying them any attention. I never rebelled back to their actions because even that ounce of attention felt like the best thing happened to me. Till this age, I never really knew what 'real' love and pure efforts felt like. I have always licked love from knives which made me bleed later. Guess? I'll never be the 'One'.
