When a relationship is going well but the idea of separation is being considered, it may be due to internal factors rather than external problems. As a relationship becomes more serious, individuals may start noticing small flaws that did not bother them before. They might need more time alone, find their partner's messages annoying, or question if they are truly in love. According to therapist John Kim, as cited in an article published in Psychology Today, fear of intimacy can sometimes push people to sabotage a relationship they otherwise want to preserve. This fear can manifest in behaviors such as avoiding deep conversations, minimizing feelings, or looking for flaws in one's partner. These reactions can serve as protective mechanisms, with some individuals provoking arguments to create distance. John Kim explains that the fear of intimacy can creep into relationships without individuals realizing it. As feelings grow, relationships demand more, sometimes requiring individuals to talk about their insecurities, express their needs, or accept that someone will discover their vulnerabilities. For some people, this closeness can become uncomfortable. According to psychologist Sandra Parker, as cited in Psychology Today, the need to control everything can sometimes arise from a difficulty in accepting one's own vulnerability. Feeling the desire to leave someone does not necessarily mean one is afraid of intimacy. It can also happen that a relationship no longer suits an individual, even when everything seems to be going well from the outside. The distinction sometimes lies in what triggers the doubts. Do they systematically appear when the other person gets closer, talks about the future, or expresses feelings? Or do they concern real disagreements, incompatible needs, or a lack of fulfillment? Taking the time to identify these differences can help avoid confusing a temporary fear with a genuine desire for separation. John Kim advises recognizing what scares individuals, which can be done through simple gestures, such as explaining to one's partner that one needs time or daring to talk about an anxiety. It is not about forcing oneself to stay in a relationship, but about understanding what really motivates the desire to leave. Loving someone also implies accepting a part of uncertainty. One can never guarantee that a relationship will work, nor can one completely protect oneself from a possible disappointment. When the desire to flee appears precisely at the moment when one begins to feel close to someone, it may be interesting to ask oneself whether it is really the person one wants to leave, or simply the vulnerability that this relationship brings forth.
