You might notice that anxiety doesn’t always show up at the beginning. At first, things may feel easy. There’s interest, curiosity, maybe even excitement. Conversations flow, and there’s a sense of possibility rather than risk. You’re responding naturally, not overthinking every interaction. In those early stages, there’s often enough emotional distance to feel safe. As the relationship develops, though, when it starts to feel more meaningful, more real, something begins to shift. The stakes feel higher, even if nothing obvious has changed. You might find yourself becoming more internally alert, as if part of you is scanning for signs that things could go wrong. It’s subtle at first. You notice yourself paying closer attention to small details. A delayed message doesn’t just register as “they’re probably busy” anymore - it lingers. A slightly different tone gets replayed in your mind. A change in routine, even a small one, can feel loaded with meaning. Things that once felt neutral now seem significant, like they might be pointing to something just beneath the surface. Alongside this, your thoughts may start to fill in the gaps. You might catch yourself trying to interpret what these shifts mean, often leaning toward worst-case explanations. “Have I done something wrong?” “Are they losing interest?” “Did I misread everything?” The mind starts trying to create certainty, but instead it often amplifies doubt. With that comes a quiet but persistent question: “Is something wrong?” It’s not always loud or dramatic. Sometimes it sits in the background, shaping how you feel and respond without you fully realising it. You might become more cautious, more self-aware, or even a little guarded. You might seek reassurance or, just as often, hold back to avoid seeming “too much.” What’s important to recognise is that this reaction isn’t random. It’s often a learned response - your mind trying to anticipate and protect you from the possibility of hurt, rejection, or disconnection. The closer something feels, the more there is to lose. For some, that’s exactly when anxiety steps in.
When closeness feels uncertain
From a CBT perspective, anxiety in relationships is often linked to how we interpret what’s happening around us. As someone becomes more important to you, the emotional stakes naturally increase. With that, certain thoughts may begin to surface:
- “What if this doesn’t last?”
- “What if they leave?”
- “What if I’m not enough?”
These thoughts can trigger anxiety, even when there is no clear evidence that something is wrong.
The beliefs behind the anxiety
These moments are often shaped by deeper beliefs, such as:
- “People don’t stay”
- “Closeness leads to hurt”
- “I could lose this at any time”.
These beliefs are usually formed through past experiences, particularly relationships where things may have felt inconsistent, unpredictable, or emotionally unsafe. Thus, when something starts to feel meaningful, your mind may become more alert, scanning for signs that something could go wrong.
Anxiety as a form of protection
Although it feels uncomfortable, this anxiety often serves a purpose. It tries to prepare you, to anticipate, to protect you from being caught off guard. However, in doing so, it can also make it difficult to fully relax into the relationship. You may find yourself overthinking, seeking reassurance, or feeling emotionally unsettled even when things are going well. Rather than seeing this anxiety as something to get rid of, it can be helpful to understand it as a response that has developed for a reason. From a CBT perspective, this involves noticing:
- the situations that trigger the anxiety,
- the thoughts that arise in those moments,
- the way those thoughts influence how you feel and respond.
With awareness, it becomes possible to create some space between the situation and the interpretation. Over time, you can begin to:
- recognise when your mind is predicting rather than responding to facts,
- gently question anxious thoughts Build a greater tolerance for uncertainty,
- develop a sense of emotional safety that isn’t entirely dependent on external reassurance.
Final thoughts
You might consider: What thoughts come up when a relationship starts to feel important? What do I fear might happen? How do I respond when that anxiety shows up? Feeling anxious when someone gets close is often rooted in understandable fears about vulnerability and loss. With greater awareness and support, it becomes possible to experience closeness with less fear—and more stability.
