When someone doesn’t tell you their plans and leaves you hanging, a few things happen psychologically:

• It creates uncertainty and stress (your brain dislikes the unknown)
• You may pause your own plans, hoping they’ll follow through
• When they don’t, it can feel like rejection or being undervalued
• And practically, you miss out on other opportunities — which builds resentment

From a psychology perspective, this often comes down to:

• Low conscientiousness (they’re disorganised or unreliable)
• Avoidance behaviour (they don’t like communicating clearly)
• Or sometimes taking your availability for granted

But here’s the key shift:
👉 The real power is in protecting your time, not trying to change them.

You can do that by setting a simple boundary:

• “If I don’t hear from you by [time], I’ll make other plans.”

This does two things:

• Removes the waiting (which is what hurts most)
• Signals that your time is valuable

And emotionally, it helps reframe things:

• It’s not “they ruined my evening”
• It becomes “I chose not to wait”

You deserve people who are:

• Clear
• Consistent
• And respectful of your time
