Iron heart

I thought you were in love but now I see it was only in my head. How could I be so stupid? So blind not to see I was the one who fought for this relationship? How could I stand by you when you were so far from me? Why did I keep waiting? Why was I in the street thinking about you when you were having fun? I tried to understand you, did you try to change? Did you try to understand what was on my mind?

You are now the past. I'll go on and I won't look back. I won't feel angry and I won't be sad because you are not going to break my heart again. My heart is now made of iron.
