Dream of disagreement, married

I am not certain but I was at my Wedding or wedding rehearsal. A minister showed up from my past in my waking life. (We had only met a few times and there we had a mutual attraction in my waking life. I met him while I was dating my husband but due to age difference and distance, we lost touch with each other). He attended but he was not invited by me or my fiancé, yet he seemed comfortable being there. He did not appear to be upset but he did not talk to anyone there, including myself. My fiancé had a disagreement and ended up not getting married in the dream (we are married in my waking life).
