He cancels plans then acts like it's no big deal: what to say back

When someone cancels and then acts unbothered, you're looking at two signals at once. The cancellation tells you this plan wasn't urgent enough to protect. The casual follow-up tells you he doesn't see a problem, or he sees one and wants to keep it light. Neither reading means he's dismissing you on purpose. But the tone is the part you can judge over time, because it's the part that repeats.

To tell the difference, look at what he does after the first cancellation. Does he propose a specific new time, or does he say something vague like "we should do something soon"? Does he put effort into the rescheduled plan, or does it quietly fade? One cancellation with a concrete alternative is ordinary. A cancellation followed by no real plan, or by cancelling again, is the pattern you're actually reacting to.

A good reply here needs to make the cancellation visible without making it a case. Say what the cancellation did from your side: you had the evening planned, you'd rearranged something, or you were looking forward to it. Keep it to one or two facts about your experience. Don't ask him to explain himself or to say he feels bad, because you'll get either a defensive answer or a hollow apology, and neither helps you.

Then move straight to what you want next. Pair the impact with a clear sign that you still want to see him. That sign should be a concrete proposal or a clear statement of interest, not a question about whether he still wants to. The point is that he should leave the exchange knowing the cancellation registered and that the plan still matters to you. If he can't respond to both parts, you've learned something useful about how he handles being called on it.

If he proposed a new time, give him room to confirm it, but don't wait longer than a day for a reply to something specific. A confirmation that comes back as "yeah maybe" or "let me check my week" should get a clear, simple yes or no from you, not an open-ended wait. If he goes quiet entirely after you've made a concrete suggestion, send one short follow-up that's easy to answer, like naming the day and asking if it works. Then stop initiating.

If the rescheduled plan falls through as well, you have your answer on the pattern, and you can decide how much more effort to spend. You don't need to deliver a speech. Just stop proposing plans and see whether he picks it up. Stopping at that point is a fair response to someone who has shown you twice that plans with you are optional. Keep your own schedule full while you wait, so the decision is about what he does and not how long you can stand the silence.
