I don't feel like i'm good enough for you anymore.
I'm second - rate and worn - out for you.
I don't really feel that close to you anymore.
Feels like you've put me aside. You see me, but i'm almost invisible to you.
Why?

What have i done? Or what have others done to you?
I've changed. I admit that. But why can't you? Why do you deny that you've changed?
You've changed the way you talk to me.
You've changed the way you look at me.
I'm second-rate to you. I'm not saying that i have to be no.1 in your heart.
I know that's too far for me, but why did you changed almost all the things you've did with me?

Its like you don't want to be close to me anymore.
You've got a new person in your life, i understand. But honestly, i feel;
UNDER-RATED.
I know i'm just being jealous, but i don't feel the closeness, the bond we used to have.
You're always with them/her/him or whoever. What happened to me?
Abandoned is it?

I've been put aside. I don't think you've noticed that.
I don't think you understand how i really feel inside.
I would tell you, i've tried a hundred and one times,, believe me but the thought that you wouldn't listen or even hear me out is trapped in my mind.

So, go on. Push me aside from you way with her/him/them.
