To "be over" someone means to have forgotten the person romantically. It's another way to say "I never stopped loving you".

"I'm Coming Over" I ohhhhh I'm dreaming of your face I can see your beauty Ten and a half thousand yesterdays. The way the moon illuminates All the secrets I've been keeping And cast them off of my balcony. Ohh I I I I I I hope you notice, That I, I'm still in love with you Yes I, I'm coming over, tonight. I'm coming over, tonight. I hope you notice I was never over you. We hold on to things we said It makes it more confusing, I wont let the past get in my way. Surrender to the eternality now, Enjoy the midnight serenade Oh I I I I I I hope you notice, That I, I'm coming over, tonight I'm coming over, tonight I'm coming over, just to say "good night" I hope you notice I was never over you I hope you notice I was never over you. My mind is crawling, But I still hear the music all around me, You found me. I I I I God I love this, If ever there was a place that I could stay, I found it I I I I I I hope you notice My love, I'm coming over, tonight I'm coming over, tonight I'm coming over, just to say "good night". I hope you notice I was never over you. I hope you notice I was never over you.
