Never gave you a chance

We used to hate each other,
That is a well known fact.
Now that I have gotten to know you,
I want to take all that back.

All the things that I used to say,
I'm really sorry for saying.
I guess now after all this time.
I'm finally repaying.

I acted like I knew it all,
And didn't give you a chance.
I tried to make you feel so small.
I never gave you a second glance.

I will be here for you,
If you ever truly need me.
Thanks for helping me through.
Your original attitude was deceiving
