Tell me if he doesn’t love me?

You are my dream of worrying about gains and losses, and I am your dispensable person. After all, the arrows that travel through mountains and rivers pierce the most affectionate people. You have to remember that if he doesn't love you, you have to love yourself. I will not keep anyone who tries to abandon me, just like I will not chew the spit out again. I'm not cold-blooded, nor am I slow-tempered. I'm just afraid that if I invest too much, I'll be sad when I leave. I don’t want to be let down, I don’t want to let others down, and I don’t want to let myself down. I just don't know, will you be sad after I leave? I thought you would understand, I thought you would stay, but I forgot that you are just a passer-by, and I am just a passer-by in your life. I thought you would look back at me, I thought you would remember me, but I forgot, I am just a passerby, and you are just a passer-by in my life.
