I can’t remember the exact order of everything that happened next.

I’m fairly certain that I collected Stephen on the same day he finally contacted me and that he didn’t stay at his ex’s for another night.

He told me it was “hell there” and that he couldn’t wait to get away.

So I did what was already becoming instinctive whenever Stephen was distressed.

I went to rescue him.

I told him to gather as much of his belongings as he could and that I would come and collect him.

In a surprisingly short space of time, Stephen managed to assemble quite a lot of his things.

That bothered me.

If he could gather so much together now, why had it been impossible to do the previous day?

I understood that his ex had needed help clearing the house, but the original purpose of the visit had been to collect his belongings. The explanation still didn’t quite add up.

And neither did the explanation about the bed.

At some point — either that evening or very soon afterwards — Stephen and I had our first enormous argument.

It happened over the phone.

I told him the relationship was over.

As far as I was concerned, he had crossed a line.

It wasn’t simply that he had shared a bed with another woman. It was that we’d discussed this exact possibility beforehand. I had told him it was the one thing I was uncomfortable with, and he had repeatedly promised me it wouldn’t happen.

His first response stunned me.

“This is why I don’t make promises!”

Really?

It hadn’t been an impossible promise to keep.

From my perspective, all he’d had to do was sleep on the sofa.

Then his whole manner changed.

For the first time since meeting Stephen, I encountered a side of him I hadn’t seen before.

He became angry.

Defensive.

Dismissive.

He told me I was blowing everything out of proportion.

“I can share a bed with a woman and not do anything,” he argued. “I have self-control.”

But that wasn’t really the point.

I hadn’t accused him of being physically incapable of lying beside a woman without having sex with her.

I wanted to understand why he’d ended up in the bed at all when he’d specifically promised me that he wouldn’t.

And that was where the explanation became increasingly difficult for me to follow.

Stephen told me he’d been completely exhausted and needed to sleep in a proper bed.

But if he’d been that exhausted, I wondered, why hadn’t he simply collapsed on the sofa where he’d told me he was going to sleep?

He said his head was so “gone” that he hadn’t really registered his ex taking him upstairs.

But she hadn’t carried him.

He had walked.

He told me he couldn’t remember much about what had happened.

Yet he could remember that he had remained fully clothed.

And he was adamant that nothing sexual had happened between them.

I kept trying to make the pieces fit together.

They wouldn’t.

Every route through the conversation seemed to lead back to the same explanation: he had been exhausted, his head had gone, he had been barely aware of what was happening and therefore hadn’t consciously chosen to break his promise.

But I wasn’t only looking for an explanation.

I was looking for something much simpler.

Accountability.

I wanted him to say:

I promised you I wouldn’t do this. I did it anyway. I understand why you’re hurt. I’m sorry.

Instead, it felt as though most of his energy was going into proving why what happened wasn’t really his fault.

And that left me feeling increasingly unreasonable for being upset at all.

There was another part of his explanation that troubled me.

If Stephen genuinely became so mentally exhausted that he could be led somewhere without properly registering what was happening, make decisions he couldn’t later remember and lose awareness of promises he’d made only hours earlier, what did that mean for me?

What could I rely upon?

For three months, I had known Stephen as gentle, affectionate, attentive and extraordinarily loving.

During that argument, it felt as though that man had temporarily disappeared.

I tried another approach.

What if it had been the other way around?

I asked him to imagine that I’d gone to stay with an ex-boyfriend, promised Stephen I would sleep somewhere else, disappeared for the night and then admitted the following day that I’d shared my ex’s bed.

Stephen said he’d be okay with it.

I didn’t believe him.

From what I already knew of his sensitivity and jealousy, I found it almost impossible to imagine him calmly accepting the same situation from me.

Eventually, the argument began to lose its heat.

And Stephen changed again.

The anger and defensiveness faded.

He became tearful.

Confused.

Vulnerable.

He talked again about how awful it had been at the house, how exhausted he’d become and how overwhelmed he’d felt.

The explanation hadn’t really changed.

But Stephen had.

This was the man I recognised again.

The wounded, struggling Stephen I’d already become deeply protective of.

And that mattered.

His distress didn’t suddenly make me think he’d done nothing wrong. I was still angry and hurt.

But it softened me.

I began wondering whether I had been too harsh.

Perhaps I needed to take his mental health into account.

Perhaps his trauma and EUPD meant that situations affected him differently.

Perhaps loving Stephen was going to require me to understand things that I wouldn’t necessarily understand in another person.

Since meeting him, I’d already been learning to consider how his past might affect him.

For the first time, I began to wonder how it might affect me.

And whether being with him would sometimes require me to tolerate things I would ordinarily find unacceptable.

There was something else I needed to understand.

Why hadn’t he tried harder to contact me?

Even if everything he’d told me about the bed was completely true, he knew I was worried about the visit. He knew what I’d asked of him.

Why hadn’t he thought about how his silence might affect me?

Stephen shrugged.

“Out of sight, out of mind.”

The words landed strangely.

I didn’t like them.

There was something unsettling about the idea that simply because I wasn’t physically present, I could somehow disappear from his emotional awareness too.

I couldn’t know then how many times I would remember those four words during the years ahead.

For now, though, I wanted reassurance.

I asked Stephen never to leave me in the dark like that again.

And I asked him never again to share a bed with another woman.

He agreed.

We decided to stay together.

And remarkably quickly, things returned to normal.

Stephen became the kind, gentle and attentive man I’d fallen for again.

We laughed.

We talked.

He was affectionate.

I felt loved and cherished.

The intensity of the argument faded, and the warmth between us returned.

But something hadn’t returned with it.

My complete sense of trust.

Before that visit, I had been relatively relaxed in the relationship.

Now there was a question sitting quietly in the background.

Can I trust him?

The incident resurfaced occasionally in the weeks and months that followed.

Sometimes it seemed as though Stephen’s understanding of what had happened would shift. Just when I thought we’d reached some kind of resolution, he would become defensive about it again.

On one occasion, while I was at work, he said something to me over the phone that I found particularly destabilising.

“Maybe you’re not ready, or don’t know how to really love someone.”

I couldn’t understand how we’d arrived there.

He had broken a promise.

I had been hurt by it.

And somehow the conversation had moved towards whether I understood how to love properly.

It made me question whether the remorse and understanding I’d thought we’d reached had ever really existed.

But I loved Stephen.

The relationship was still new, passionate and overwhelmingly good most of the time. I had also begun to understand him as someone carrying significant wounds of his own.

So I chose to believe that this was something we could learn from.

I believed the boundary had now been made unmistakably clear.

I believed he understood how deeply the incident had affected me.

And I believed that because he loved me, he wouldn’t put me through something like that again.

I didn’t know then whether the night with his ex was an unfortunate mistake, a warning, or something more significant.

I only knew that for the first time since falling in love with Stephen, love no longer felt quite enough on its own.

Trust had entered the conversation.

And once I had started wondering whether I could trust him, I could never entirely stop.
