Social Media and Relationships: How Instagram Is Destroying Couples

Social media has fundamentally altered the landscape of romantic relationships. What was once private — arguments, affection, milestones — is now performed, curated, and judged in a public arena. A study by the American Psychological Association (2023) found that 65% of adults believe social media has a negative effect on romantic relationships, yet the average person still spends over two hours daily scrolling through feeds. The paradox is clear: we know it harms us, and we cannot stop.

Platform Primary relational risk Mechanism
Instagram Comparison and idealisation Curated perfection creates unrealistic benchmarks
TikTok Normalisation of toxic dynamics Viral "relationship advice" often lacks nuance
Twitter/X Conflict amplification Public arguments and airing grievances
Dating apps Temptation and micro-infidelity Infinite perceived alternatives
Facebook Ex-partner surveillance Easy access to former partners' lives

The Comparison Trap: Why Other Couples Always Seem Happier

Social media researcher Mai-Ly Nguyen Steers (2014) demonstrated what she calls the social comparison spiral: the more time you spend on Instagram, the more you compare your relationship to curated highlights of others — and the worse you feel. You see their anniversary dinner, not their argument in the car on the way home. You see the surprise flowers, not the three weeks of silence that preceded them.

Gottman's research is unequivocal: the number one predictor of relationship dissatisfaction is unfavourable comparison. When you think "other couples have it better," you begin to perceive your partner through a lens of deficit rather than gratitude. Social media industrialises this comparison at scale.

Micro-Infidelity: The Grey Zone

The term micro-infidelity, coined by psychologist Martin Graff (2019), refers to small actions that blur the line between innocent social interaction and emotional betrayal:

  • Liking an ex's selfies consistently
  • Maintaining a "just friends" DM conversation with someone you are attracted to
  • Hiding certain online interactions from your partner
  • Keeping dating app profiles "just in case"

None of these individually constitute infidelity. But collectively, they create what Esther Perel calls a "parallel emotional world" — a space where energy, attention, and emotional intimacy are diverted away from the relationship.

Phubbing: The Death of Presence

Phubbing — phone snubbing — is the act of ignoring your partner in favour of your phone. A study by James Roberts and Meredith David (2016), published in Computers in Human Behavior, found that phubbing directly predicts:

  • Lower relationship satisfaction
  • Higher levels of depression in the ignored partner
  • Increased conflict frequency
  • Reduced feelings of intimacy and connection

The cruelty of phubbing is its banality. No one intends to hurt their partner by checking Instagram during dinner. But the message received is: "This screen is more interesting than you are."

How Social Media Amplifies Jealousy

Jealousy is not new; social media simply gives it a 24/7 feed. Research by Muise, Christofides, and Desmarais (2009) found that Facebook-specific jealousy is a measurable phenomenon: the more time a person spends on their partner's profile, the more jealous they become, regardless of whether there is any actual threat. The human brain is not designed to have unlimited access to a partner's social interactions — it interprets ambiguity as danger.

Common triggers:

  • Unknown people commenting on or liking your partner's posts
  • Your partner being tagged in photos with people you do not know
  • Delayed responses to your messages while they are clearly active online
  • Stories or posts that suggest activities you were not told about

What You Can Actually Do

  1. Negotiate social media boundaries: this is not about control — it is about transparency. Ask each other: What feels comfortable? What feels like a violation? Are we okay with posting about our relationship? Can we agree to put phones away during meals?
  2. Practice digital presence: when you are together, be together. Set phone-free zones (bedroom, dining table) and phone-free times (first hour of the morning, last hour before bed).
  3. Discuss micro-infidelity openly: "I noticed you've been messaging X a lot. Can we talk about it?" is healthier than silent surveillance or passive-aggressive likes.
  4. Curate your feed consciously: unfollow accounts that trigger comparison. Follow accounts that model healthy, realistic relationships.
  5. Address phubbing directly: "When you check your phone while I'm talking, I feel invisible" is a legitimate boundary, not a demand.
  6. Use technology for connection, not comparison: tools like LetsShine.app use technology to strengthen relationships rather than erode them — offering guided conversations that replace the shallow dopamine of scrolling with genuine emotional connection.

The Positive Side of Social Media in Relationships

It is not all destruction. Research by Toma and Choi (2015) found that couples who post about their relationship in a balanced, authentic way report higher satisfaction — not because of the post, but because the act of publicly affirming the relationship reinforces internal commitment. The key word is "balanced": performative oversharing signals insecurity, while genuine occasional sharing signals pride.

Long-distance couples also benefit enormously from social media as a way to share daily life across the miles. The tool is neutral; the intention behind its use determines whether it builds or erodes connection.

Frequently Asked Questions

Is it controlling to ask my partner not to like certain people's posts? It depends on the intent. If it comes from insecurity and you want to control their behaviour, work on the insecurity first. If a specific behaviour has been discussed and agreed upon as a boundary, enforcing that boundary is healthy.

Should we share our phone passwords? There is no universal answer. Some couples find it builds trust; others find it unnecessary if trust already exists. What matters is that the decision is mutual and not coerced.

My partner posts about us constantly but is distant in private. Is that a red flag? Yes, it can be. Performative social media affection that contrasts with private disconnection is worth addressing. The relationship should feel real offline, not just online.

How do I stop comparing my relationship to what I see on social media? Awareness is the first step. Remind yourself that you are comparing your full reality to someone else's highlight reel. Then reduce exposure: mute, unfollow, or take social media breaks.
