My partner announced my quit-smoking date to the family. How do I take it back?

At Sunday lunch my partner said, "Two weeks from Monday, no more cigarettes." My aunt applauded. I had not chosen a date.

I had told him I was talking to a pharmacist about a quit plan. He took that as permission to make it public because he thought a crowd would keep me motivated. I spent lunch nodding, then bought cigarettes on the way home and felt as though I had already failed something that had not started.

He is tired of smoke coming in through the back door, which is a fair household complaint. I am tired of conversations about it becoming a performance for relatives.

[CDC provides resources for making a quit plan and getting support](https://www.cdc.gov/tobacco/campaign/tips/quit-smoking/index.html). I want to use support, but I need to agree what it looks like.

How do I correct the family announcement without turning it into a promise that I will never set a date?
