Why so cold

Your eyes changed when I came close, short replies.
No emotions.
Late at night, you feel far, different soul,
Different heart.
Why so cold?
Tell me now.
We were fire, what are we now?
Why so cold when I stay?
You look at me, then fade away.
Empty words, empty tone, even near, I feel alone.
Something broke in your voice, losing you without a choice.
Why so cold?
