You lost me

I don't know how to say i forgive you,
all i can say is I'll try,
i don't no how to talk to you,
when all i can do is cry,
i do know if our sun will shine,
when your hearts no longer mine,
i don't know how to fight for you,
when shes standing in my place,
i hope her friendships special,
because she made you lose a best friend,
a friend that would,
stand by you in a battle,
hold you strong when your weak,
who would step forward when the world steps back
a friend for life, i hope she was worth it,
