3 Diabolic Reasons Single Women Sabotage Their Friends' Relationships

Ladies and gentlemen, you’re a 4 minute read away from relationship enlightenment.

In the messy world of friendships and romance, there’s a dark undercurrent that doesn’t get talked about enough: single women who sabotage their friends’ relationships. It’s a topic that sparks heated debates on X and in group chats alike, with countless stories of betrayal and heartbreak pointing to a pattern that’s hard to ignore. While not every single woman is out to ruin her friend’s love life, there are some who — whether consciously or not — engage in behaviors that can tear relationships apart. Why would someone do this to a friend? The reasons are often more sinister than you’d think, rooted in deep psychological and emotional drives. Here are three diabolic reasons single women might sabotage their friends’ relationships — and why this toxic behavior is more common than we’d like to admit.

Reason 1: Envy Fuels a Desire for Control

Let’s start with the most primal driver: envy. When a single woman sees her friend in a happy, thriving relationship, it can stir up feelings of jealousy that she might not even admit to herself. In 2025, the dating landscape is tougher than ever. A 2024 report from the Pew Research Center found that 47% of single adults in the U.S. say dating has become harder in the last decade, citing economic pressures, dating app fatigue, and shifting social norms. For a single woman struggling to find love, watching her friend get showered with affection — date nights, sweet texts, maybe even an engagement ring — can feel like a punch to the gut.

That envy can morph into a diabolic need for control. By sabotaging her friend’s relationship, she regains a sense of power over her own narrative. She might plant seeds of doubt, like saying, “Are you sure he’s really over his ex?” or “I heard he was flirting with someone at that party.” These subtle digs can erode trust over time, creating cracks in the relationship. A 2023 study published in the Journal of Social and Personal Relationships found that 29% of women admitted to feeling jealous of a friend’s romantic success, and of those, 14% acknowledged acting on that jealousy in ways that harmed the relationship — like spreading rumors or giving bad advice. The single woman might not even realize how destructive her actions are; she’s just trying to feel better about her own loneliness by bringing her friend back to her level.

Reason 2: Fear of Losing Emotional Intimacy Drives Manipulation

Friendships between women often involve a deep emotional bond — late-night talks, shared secrets, and unwavering support. But when one friend enters a serious relationship, that dynamic can shift. The partnered friend might have less time for girls’ nights or long phone calls, redirecting her emotional energy toward her partner. For a single woman who relies on that friendship for emotional intimacy, this change can feel like abandonment, triggering a diabolic urge to sabotage the relationship to reclaim her friend’s attention.

This fear of loss can lead to manipulative tactics. She might guilt-trip her friend, saying things like, “You’ve changed since you started dating him,” or “I guess I’m not important to you anymore.” She might even go further, creating drama to pull her friend back in — like picking fights over unrelated issues or exaggerating her own struggles to demand more attention. On X, users have shared countless stories of this behavior, with one viral thread from May 16, 2025, detailing how a single friend invited her coupled-up bestie to a “girls-only” trip, only to spend the whole time badmouthing the boyfriend and trying to convince her to break up. A 2022 study in Personality and Social Psychology Bulletin found that fear of losing a friend to a romantic partner can increase competitive behavior, especially among women who feel emotionally dependent on the friendship. The single woman’s sabotage isn’t just about jealousy — it’s a desperate, diabolic attempt to hold onto the emotional closeness she craves.

Reason 3: A Twisted Sense of Superiority Fuels Destruction

Here’s where things get truly dark: some single women sabotage their friends’ relationships because they genuinely believe they’re “saving” them, driven by a twisted sense of superiority. In the age of social media, where ideologies clash daily, some single women adopt a mindset that romantic relationships — especially traditional ones — are inherently oppressive or a betrayal of independence. This belief is often amplified by cultural trends like the “4B movement,” which gained traction in the U.S. in 2024, encouraging women to reject dating, marriage, and motherhood as a form of feminist resistance. While the movement has its merits for some, it can also breed a toxic superiority complex in others.

A single woman with this mindset might see her friend’s relationship as a personal failure — a sign that her friend has “given in” to societal pressures. She might sabotage the relationship under the guise of “helping,” saying things like, “You don’t need a man to be happy,” or “He’s holding you back from your true potential.” Her actions can escalate to outright interference, like encouraging her friend to flirt with other people or orchestrating situations where the boyfriend looks bad — like “accidentally” inviting an ex to a group hangout. A 2024 survey by the American Psychological Association found that 19% of women admitted to projecting their own beliefs onto a friend’s relationship in ways that caused conflict, often justifying it as “looking out for their best interest.” This diabolic behavior isn’t just about ideology — it’s about asserting dominance, proving that her way of life is “better” by destroying what her friend has built.

The Bigger Picture: A Toxic Cycle We Need to Break

These three reasons — envy, fear of loss, and a superiority complex — paint a chilling picture of why some single women sabotage their friends’ relationships. It’s a toxic cycle fueled by insecurity, emotional dependency, and cultural pressures. But it’s not just the sabotaged relationships that suffer; the friendships often crumble too. A 2023 study in the Journal of Friendship Studies found that 41% of women reported losing a close friend after a romantic relationship ended due to external interference, often citing trust issues as the reason.

This issue remains a hot topic on platforms like X, where users share stories of betrayal and debate the ethics of meddling in a friend’s love life. The truth is, not every single woman is out to ruin her friend’s relationship — but the ones who do often act out of deep, diabolic impulses they may not fully understand. Addressing this behavior starts with self-awareness and honest conversations. If you’re a single woman feeling resentful of your friend’s happiness, or if you’re in a relationship and suspect sabotage, it’s time to confront the issue head-on — before the damage becomes irreparable.
