I came in like a wrecking ball
I never hit so hard in love
All I wanted was to break your walls
All you ever did was wreck me
She felt that the worst she would did was loving him faithfully but he was wreck it. He wreck her heart. And after all the she do he only replaces to break her heart.
So loving the person who doesn't loves you back maybe that's the worst but in her case, maybe it's different.
