Fiancé disappeared on Nikah day

I need help understanding what happened to me and whether it relates to a mental health issue.

On the day of my Nikah, my fiancé and his entire family disappeared without warning. I only found out through the hotel front desk. A couple of hours later, he called to tell me he didn’t want to marry me. He claimed that he and his family had prayed Istikahara and decided against the wedding. When I expressed my concern about how this would affect my father—who had recently undergone open-heart surgery—he abruptly disconnected the call.

The night before, he had attended the pre-wedding event with his family and promised me he would be on time for the ceremony. I was completely blindsided. None of it makes sense.

Throughout our relationship, he came across as charming, kind, shy, modest, and incredibly similar to me. It felt almost too perfect at times—like he always had the ideal response to my questions and mirrored so many of my values and interests. He often spoke about being very close to his mom and sister, and his family was involved in our relationship from the beginning. Looking back, I now realize that when I asked him difficult or probing questions, he would often deflect or step away, only to return later with what seemed like a carefully crafted, perfect answer.

Early on, he joked about being a "chameleon," a comment I didn’t think much of at the time. He also shared stories of childhood trauma, including how his mom and sister were mistreated by their in-laws. He emphasized how strongly he believed in emotionally supporting his wife, which made me trust him deeply. I saw him as someone who valued compassion, family, and partnership.

And yet, despite all of this, he disappeared on the day of our wedding. I’m struggling to reconcile how someone who seemed so kind, genuine, and aligned with me could do something so hurtful and cold. Why didn’t he have the courage to meet with me in person before leaving? How could someone who presented himself as caring and trustworthy be capable of this?

Adding to the confusion, I reached out to his family after he left, but no one responded. Initially, his family seemed fully involved in the wedding planning, but I now realize there were signs that something was off. For example, he had told me they were bringing 150 guests, yet at the pre-wedding festivities the day before, only 10 of their immediate family members attended. It’s like they had been pulling away without me noticing.

I’ve been reflecting on the relationship and wondering if I missed any red flags. Was his behavior a sign of deeper mental health issues, or was it something else entirely? I’ve been researching personality disorders and manipulative behavior, but I don’t know if those apply to him or what I experienced.

I’m focused on my own healing, but I’m haunted by unanswered questions. Has anyone else gone through something like this? I would appreciate any insight that might help me make sense of it all.
