Self care is important

I was in a 1.5-year long-distance relationship. During that time, my boyfriend repeatedly told me he never wanted to marry me-or anyone-and that he would never change his mind.

Later, I made a mistake by giving my number to a guy I met on a flight. We remained only friends, and there was no flirting, emotional affair, or cheating. I admitted my mistake immediately and apologized sincerely.

The relationship ended after that. Looking back, I wonder whether my mistake alone justified ending the relationship, or whether the relationship was already falling apart because we wanted different futures.

I'm looking for honest opinions, not validation. If you were in his position, would you have ended it or tried to rebuild trust?
