If a girl and a boy decided to stop being in a relationship and wait until allah brings them together ..is it permissible?

I've had a crush on a boy when I was small cause of his character,personality and everything.but I never told anyone about it and prayed to allah daily for his goodness,health and everything.i didnt see him after he changed school.but I had hope and never stopped praying to allah for his success both in world and akhirah.i had no idea where he was still didn't give up. While scrolling through social media I found him and even though I didn't want any relationship at that moment I wanted to tell how much he meant to me.that moment I came to know he had loved me too but he didn't know how to say and he thought that I was a good girl and won't take it in a nice way.but we started talking casually. But later on decided to stop for the sake of allah and wait until our marriage. And let him bring the proposal and let it be a proper halal arranged marriage and no one needs to know about the past except him,me and Allah..is this the right decision?
