What to text when he reschedules twice then acts blindsided

One reschedule happens. Work runs late, plans fall through, life gets messy. Twice is a pattern. By the second reschedule, he's shown you this isn't a high priority and he doesn't factor in your time as something finite or valuable. The surprise reaction afterward is the real signal. A person who actually respects you knows they've pushed their luck and apologizes differently. They don't act like you're being unreasonable for noticing. His shock is either real (meaning he doesn't see the problem) or performed (meaning he's hoping you'll feel guilty). Either way, this is information about how he operates.

First, it ends the back and forth without reopening a debate. You're not negotiating whether you're right to be annoyed. You're not defending your boundary. You're stating it once and stopping. Second, it doesn't let his reaction pull you back in. When he acts hurt or blindsided, your instinct is to fix it, explain it, or give him another chance. Your text needs to leave no room for a meaningful reply that would keep you typing. You want him to understand that the conversation is closed, not that he has a chance to convince you otherwise.

Set the boundary in one message and then stop responding to that thread or respond only to something entirely new. If he tries to re-litigate, like 'But I really do want to see you' or 'I'm sorry, one more chance?', you don't owe him a thoughtful reply. Short acknowledgment or silence. Don't disappear from his other messages for days because that can read as playing hard to get. But don't resume a flirty tone or act like this is still on the table. If he respects the boundary and comes back weeks later with real plans, you can decide then whether to trust him. If he doesn't come back, or comes back immediately with 'Can we talk about this?', that tells you he doesn't respect your time.
