“Tell Me Lies”: Why We Can’t Stop Watching the Most Toxic Relationship on TV

Okay, we need to talk about it. All of Ireland, and the rest of the world for that matter, seems to be obsessed with one thing right now: Tell Me Lies. It’s that series which on the surface is about college love, but in reality is a masterclass in showing how a relationship can twist and turn your self-esteem until you hardly recognise yourself anymore.

We devoured Tell Me Lies - Season 1, hook, line and sinker. Remember that feeling after the season finale? When you just sat there, completely drained, wondering how you got so invested in two people who are clearly on a path to destroy each other? Lucy and Stephen – names that have become synonymous with a guilty pleasure addiction. It’s like belting out "Tell Me Lies, Tell Me Sweet Little Lies" at karaoke, while deep down you know the truth is the only thing that can save you.

And now, with Tell Me Lies - Season 2 on the horizon (or for those who’ve already binged the episodes), the conversation is hotter than ever. I’ve been biting my nails watching it, and it hits me every time: why do we do this to ourselves? Why do we crave more of this angst?

It’s not just a guilty pleasure. It’s something deeper, something that the psychology behind destructive relationships actually has an explanation for. It’s as if the writers took a course in attachment theory and turned it into a TV show. The dynamic between Lucy and Stephen is so skilfully crafted that it taps into something primal in all of us.

• That rollercoaster is designed to be addictive: Just like in real toxic relationships, Stephen alternates intense warmth with icy distance. When he finally throws Lucy a crumb of affection after days of silence, it releases dopamine in our brains – and in hers. We literally become addicted to waiting for the next "high".
• No one is just a victim or a perpetrator: What makes the series painfully good is that we see Lucy’s own destructive patterns. We see her lie, manipulate, and push away anyone who tries to save her. It’s not a classic good-versus-evil story, but a terrifyingly realistic portrayal of how two damaged people can turn each other’s vulnerabilities into weapons.
• Nostalgia that stings: For those of us who were in college in the early 2000s, it’s like stepping into a time machine. The music, the clothes, that feeling of being young and believing everything was life or death. The series captures that intensity – that feeling that this person is your entire world, even when everyone around you is telling you to run the other way.

That’s probably why we keep coming back to Tell Me Lies. We see our own stupid decisions, our own "I-can-fix-him" moments, or perhaps someone else’s, reflected on the screen. It’s a reminder, a warning, and for some, a comforting thought that you weren’t alone in going through something similar.

Whether you’re rooting for Lucy, despising Stephen, or just here for the drama (no judgement, promise), one thing’s for sure: the buzz isn’t going anywhere. And me? I’ll be glued to the screen until the very last second of Tell Me Lies - Season 2, probably with a pillow in front of my face, shouting at the TV. Because that’s exactly the kind of relationship we have with this series – it’s impossible to let go of, even when you know it’s not good for you.
