Try this
- State what no longer fits and whether you want a replacement. Keep a replacement optional if your actual need is less structure.
- Clarify when the change starts so neither person continues planning around the old arrangement.
A worked example
“I want to stop the daily photo exchange from this week. I enjoyed parts of it, but I’d prefer spontaneous updates now.”
An invented example to adapt, not a real exchange or a script you have to follow.
Before you leave it here
Do not frame stopping as a temporary break if you mean to end the routine. Clear wording prevents an unspoken expectation that it will automatically resume.
