What to Do When a Friend Keeps Canceling Plans at the Last Minute

Don't address each cancellation individually -- that becomes nagging. Instead, name the pattern calmly and with curiosity, not accusation. "I've noticed we've had a few cancellations lately. Is everything okay, or should we find a format that works better for you?" This opens a door rather than closing one. Sometimes people cancel because they're struggling; sometimes because the format doesn't suit them. Either way, the pattern is the conversation, not the individual no-show.
