Lost cause

I never realize loving someone is so hard.
You said we were meant for each other.
Still I failed u.
I thought if I did my best and no matter what it takes,
I could still take good care of u.
If only I have a pair of wings, I would fly to u
But it’s just not something that I could do.
I wish I could keep on smiling,
But u just won’t let me be.
Please tell me, what should I do now?
Sorry for writing this down, it keeps bothering me.
Suppose I leave it up to u,
Just be true to your heart
I respect your every wish and demand.
But if it is up to me,
I’ll say, let’s keep on living our dream.
