Scared to say I love you

What do you do when
The one you love thinks
You don't love him even though
You would do anything to keep him happy

Sometimes i don't understand you
You change randomly and i am scared
Scared to say i love you to
Because you have broken my heart many times before

You always ask if I'm alright
I say yeah I'm fine
But the truth is I'm not
I'm really hurting inside
