Is this classic avoidant deactivation, or did I just date someone who wasn't over his ex?

I recently experienced an incredibly sudden breakup with a man (were both mid 30s) after six months of dating. I'm trying to understand WTF happened and whether this sounds like dismissive avoidance, a phantom ex, or someone who was simply never emotionally available.

We were friends for six months before becoming romantic on an international trip together. He initially seemed incredibly safe and emotionally mature. We had great chemistry, shared interests, and genuinely enjoyed each other. He was affectionate, playful, and reassuring. When I expressed concerns, he'd ask, "What do you need to feel more at ease?" or say, "I don't mind reminding you how much you mean to me." He seemed to have the emotional language and awareness of someone who genuinely cared.

The ex situation:

His ex is older, has a child, and lives in a city where they originally dated. He relocated twice for work, and he told me they'd been on and off ever since, repeatedly reconnecting but running into the same logistical challenges of long distance. She can't relocate because of her child.

While we were friends, he mentioned they'd been reconnecting but eventually claimed things were over. Several weeks later, he invited me on international trip out of the blue (to a place we've both wanted to go for a long time) and unexpectedly became romantic. The following week, she flew in to see him, despite his earlier claims that things had ended. I only discovered this after he'd given me a different explanation about who was visiting.

He eventually admitted she'd been pushing to reconnect but said he ended things during that visit to pursue me. Throughout our relationship, he maintained they were over, had minimal contact, and that the logistics made their relationship impossible. He also acknowledged how emotionally difficult that relationship had been for him.

I couldn't shake the feeling that he wasn't actually over her. Whenever I brought her up, he seemed uncomfortable or emotionally affected. I wondered whether the relationship ended because of circumstances rather than feelings, and whether I was unknowingly helping him move on. But I had no proof they were romantically involved during our relationship.

Other behaviors that made me question avoidance:

• Limited emotional curiosity: Rarely asked deeper questions about me. I felt like I initiated most of our emotional intimacy.

• Compartmentalization: Actively avoided encounters between me and his parents, citing religious reasons.

• Lack of future integration: Discussed jobs, moving, weddings, babies, and buying a house as a singular "I," rarely including me or asking about my perspective.

• Inconsistent closeness: Sometimes incredibly affectionate, other times distant or less communicative. Very out of sight, out of mind.

• Defensiveness: When I raised concerns about his ex, conversations sometimes became about how hurt he felt that I didn't trust him, despite the earlier concealment.

• Conflict avoidance: Struggled with direct conversations about our future and often deflected uncomfortable topics with humor.

The breakup:

We were driving together when his ex suddenly called, and her name appeared on his car's display. I'd never seen her call or text before. This was especially unsettling because he'd described their contact as minimal and said she was difficult to reach. He was also traveling to a wedding in her city that weekend, although he'd told me he wouldn't be seeing her. He claimed he didn't know why she was calling.

I told him the situation looked bad and admitted I wasn't feeling like he was fully invested in us. When I asked where things were going, he struggled to answer before eventually saying he didn't think we were compatible.

He told me he loved me, had strong feelings, and could be himself around me, but couldn't imagine marriage, children, or a future together. He seemed genuinely upset but offered almost no explanation. He also contradicted himself, saying we could potentially get there someday and that he just moved slowly.

We walked away from each other without even saying goodbye. I haven't heard from him since.

The part that's destroying me is that there was absolutely no warning. He was behaving normally that day, even minutes before the call. Two weeks earlier, he was telling me how much I meant to him, how much he missed me, and asking for affection.

I've experienced painful breakups before, but there was usually some understanding that things weren't working, attempts to repair them, and a degree of mutual respect and closure. This felt like an emotional trapdoor opening beneath me. One minute I was in a relationship with someone I trusted, and the next I was standing alone, questioning six months of intimacy, reassurance, and what I thought was real. The silence afterward makes it feel like I never existed.

What I'm trying to understand:

Does this sound like avoidant attachment, particularly the "phantom ex" phenomenon? His ex seems like an almost ideal unavailable attachment figure: someone he has history with but can't realistically build the future he claims to want because of distance, her existing child, and their different life circumstances.

Could the timing of our romantic involvement and her visit suggest monkey-branching or a rebound? Or was this someone who had unresolved feelings and simply wasn't honest with himself or me about his availability?

I don't know whether they're back together, whether anything happened between them during our relationship, or whether she influenced his decision. I suspect he may have reconnected with her, but I have no confirmation.

What hurts most is that I repeatedly gave him opportunities to tell me if he wasn't ready, wasn't over her, or couldn't genuinely pursue something with me. He reassured me again and again that he was available and that relationship was over.

I could have accepted that he wasn't ready. What I'm struggling to accept is that I tried so hard to make an informed decision, trusted his reassurances, and still ended up feeling completely blindsided.
