You Left me Hollow

My world has crumbled and you can care less,
Why should you care when you've in fact found happiness,
I'm sitting here wishing you'd come back to me so my heart will no longer bleed,
but as sad as I am your only excuse is "This is what I need"
It feels like it can't be true, I never wanted this and neither did you,
But once again I must be wrong cause obviously this is what you wanted to do,
Be single be free, love anybody new that you wanted to,
But what good does it do when you break the one you "Love" the most of all,
unless you lied and didn't care how hard in fact that would fall,
as long as your happy living your life like you intended,
and just laughing at the life I fell in love with that you must have pretended
