Have you ever fallen for your ex a second time? I need a song about this please?

Me and my ex recently have started seeing each other again but we
didn't hookup. I think we're both scared to do this all over again.
But I miss him....i need him again. But at the same time im
hesitating. It's a push and pull kind of thing. I need affection. I'm
scared. Any songs about falling for a love that fell apart?

THanks
