I thought I could made it~but I can't

I thought I could just forget you so easily when the day you left me for that girl..
I thought I could brave enough to leave you with no doubts and sadness..
I thought I could not love you anymore after I was hurt by you again and again..
I thought I could never look back and think of you anymore..
I thought I could just give up this relationship and you..
I thought I could just pick some other guy to replace you in my heart..
I thought I could just erase the memories I am with you for the past 3 years..
I thought I could forget you already after I had deleted all the messages which you sent to me..
Everything also I thought I could~
But I was totally wrong..
I could not forget you easily ever since you left me..
I am not brave enough to leave you without sadness..
I could not stop loving you even though I was hurt again and again..
I looked back and think how wonderful life was when I was with you..
I could not just give up you and also this amazing relationship..
I could not find anyone to replace you in my heart..
I could not forget how wonderful life was when I was with you for the past 3 years..
I could not even forget a bit about you even though I had already deleted all the messages which you sent to me..
That's the mistakes which I have made..
