My Fiancé Chose His Mistress Over Our Future

I discovered the truth in the most mundane way possible: through a phone bill.

Jonah had left his laptop open on our kitchen island while showering, his email displaying a notification for his monthly statement. I wasn't snooping—I'd simply glanced at the screen while refilling my coffee, but what I saw stopped me cold. Two hundred and seventeen calls to the same Seattle number in just three months.

I knew that number. It belonged to Lily Summers.

With trembling fingers, I clicked the statement open. The pattern was unmistakable—calls to Lily during every significant moment of our relationship. A forty-minute call the night Jonah first told me he loved me. Three calls the day we went apartment hunting. A ninety-minute conversation that started precisely twenty minutes after he proposed.

Each memory, now tainted with the knowledge that he'd immediately run to Lily afterward.

When Jonah emerged from the shower, hair damp and a towel around his waist, I was sitting at the island, the laptop turned toward him, the evidence illuminated on the screen.

"Care to explain this?" My voice sounded calmer than I felt.

He glanced at the screen, his expression shifting from confusion to defensiveness in seconds. "You went through my phone records?"

"They were open on your laptop. Two hundred calls, Jonah. Including one the night you proposed to me."

He sighed, running a hand through his wet hair. "They're medical emergencies, Ivy. You know about her condition."

"Every single time something important happens between us, you call her. Or she calls you. That's not coincidence."

"She needs me." His voice hardened. "She took a bullet for me, Ivy."

"And you've repaid that debt a thousand times over." I stood up, my coffee forgotten. "What about what I need? What about our relationship?"

"Are you seriously jealous of someone's trauma?" Jonah's face flushed with anger. "That's beneath you."

The accusation stung like a slap. "This isn't about jealousy. This is about boundaries. About priorities."

"My mother warned me about this," he muttered, turning away.

"Your mother?" I followed him into our bedroom. "What does she have to do with this?"

Jonah pulled a shirt over his head, not meeting my eyes. "She said you might have trouble understanding the situation with Lily. She's been helping me... manage your expectations."

The room seemed to tilt sideways. "Manage my expectations? Like I'm some problem to be handled?"

"That's not what I meant—"

"It's exactly what you meant." My voice cracked. "Your mother has been coaching you on how to keep me in line while you prioritize Lily."

The fight escalated from there, words flying like shrapnel, neither of us willing to back down. When it finally ended, we'd reached an uneasy stalemate—one that felt like the first crack in what I'd thought was unbreakable.

Three days later, I stood in Maya's gallery surrounded by the vibrant work of Indigenous artists she'd spent months curating. This opening should have been a professional triumph for her and a welcome distraction for me. Instead, I felt a familiar dread when I spotted Lily Summers walking through the door.

She was wearing Jonah's Columbia jacket—the one he'd worn on our first date. Her blonde hair fell in perfect waves around her shoulders, and she moved through the crowd with practiced fragility, as if the world might shatter her at any moment.

"What is she doing here?" Maya whispered, appearing at my elbow with two glasses of champagne.

"I have no idea." I accepted the drink gratefully. "Jonah said he couldn't make it tonight."

Lily spotted me and made a beeline across the gallery, her expression a carefully constructed mask of warmth.

"Ivy! There you are." She air-kissed both my cheeks. "Jonah felt terrible he couldn't be here to support you, so he asked me to come instead. Wasn't that thoughtful?"

Beside me, Maya made a choking sound.

"This is Maya's event, not mine," I said, gesturing to my friend. "Maya, this is Lily Summers."

"I know exactly who you are," Maya said with a tight smile that didn't reach her eyes.

Lily barely acknowledged her before turning back to me. "Jonah talks about you constantly, you know. He's so worried about the pressure you're under with the wedding."

She linked her arm through mine, effectively trapping me. "Did he tell you about my latest PTSD episode? The fireworks last weekend triggered the most awful flashbacks to the shooting. Jonah understands trauma in ways most people can't."

For the next hour, Lily shadowed me through the gallery, loudly discussing her "triggers" and "episodes" within earshot of Vancouver's most influential art patrons. I watched Maya's carefully planned event become background noise to Lily's performance of fragility.

A silver-haired museum director I'd been cultivating for months approached me near a striking mixed-media piece. "Fascinating work," she said, before lowering her voice. "Ivy, dear, are you... okay with this arrangement? It seems rather unconventional."

Lily, hovering nearby, smiled sweetly.

In that moment, I understood with perfect clarity: this wasn't about trauma or gratitude or obligation. This was warfare, and I was losing ground with every sympathetic glance thrown Lily's way.
