He better of with someone else

It's  for the best, I know it is

But I see he...

Sometimes I try to hide what I feel inside

And I turn around

He with her now 

Tell me why he's so hard to forget 

Memories supposed to fade

Didn't think I'd be this hard

What's wrong with my heart??

I just can't figure it out

I never understand

And I really don't know what to do
