In a committed relationship, it can be difficult to determine when emotions or attractions toward someone else might cross the line into infidelity. The question arises: does simply being attracted to another person pose a risk to the relationship? Long-term relationships often face various challenges, such as disagreements, differing views, fading romantic feelings, emotional distance, and infidelity. These factors can strain or even end a relationship. However, the line between harmless attraction and actual infidelity can be unclear. Gérard Leleu, a sexologist and psychotherapist, suggests that true fidelity in love involves being fully committed—emotionally, physically, and mentally—to one's partner. Yet, if attraction to someone else is not considered infidelity, then what does that mean for relationships built on exclusivity? A study published in The Journal of Sex Research in February 2024 explored this issue. Researchers Charlene Belu and Lucia O’Sullivan surveyed 542 people aged 22 to 35 who were in monogamous relationships for at least three months and had developed a crush on someone else. Participants answered detailed questions about their crush, their relationship with that person, and their level of satisfaction and commitment with their current partner. They completed the survey twice, four months apart. The findings revealed that having an interest in someone else is relatively common in relationships. Over two-thirds of the participants (67.7%) had not shared their crush with their partner. On average, participants had known their crush for about two years and felt attraction for about one year. However, only 3% of the participants had cheated on their partner with their crush by the second survey. This suggests that simply being attracted to someone else does not necessarily lead to infidelity. The researchers also found that attraction to another person is influenced by how satisfied one is in their current relationship and how much they invest in it. If someone is less satisfied or feels less committed to their partner, they may be more likely to be drawn to someone else. While having a crush is not inherently a threat to the relationship, strong feelings of attraction could indicate underlying issues that might affect the relationship’s stability.
