Cate - Rocket Science (song) release date?

About the single "Cate - Rocket Science":

You said you were really trying
But babe, love me, it isn't rocket science..

Yeah, It would've been nice to get a morning text
It would’ve been sweet if you stopped seeing your ex
But I know, it's out of your control
And it would've been cool if you liked my friends
I would’ve felt lucky if you kept your plans
But I know, you have places to go.

Oh, crazy was something you made me
When you started saying I was "Difficult"
And stupid was you blew it..
