<human>: So I really like my boyfriend. We get along really well and smoking isn't a deal breaker for me. I don't smoke, and it doesn't bother me that he does.

It does bother me that he'll often tell me (at least three times a week) "I want to quit," or "I'm going to quit." This has turned into him joking about how he'll quit the tomorrow after tomorrow, or justifying his smoking by saying how awesome it is socially, etc. 

The part that bothers me is that he'll tell me he's going to stop smoking, I tell him I'll support him however he needs and if he wants I'll buy him toothpicks or hang out with him to distract him or whatever. Then he quits for a day, then I'll see him and he'll have a pack of cigarettes in his pocket and he'll act like he never pretended to quit in the first place. It kind of drives me crazy.

I'm not out looking for advice on how to get him to quit, because it's his life and his decision and I honestly don't mind it that much. 

I'm looking for advice to be able to tell him, in a more graceful way, "Please stop telling me you want to quit if you have no intention of actually quitting." It's just annoying, and I care about him and I worry when he says he's going to quit because I know it's stressful and sucks and I want to support him, but I don't like being told something then having it not last at all. It would be different if it was, you know, he quits for a week or a month or *tries* but he doesn't try at all.

Condense the text into a few key points
<bot>: Boyfriend keeps saying he wants to quit smoking then doesn't, I don't know how to tell him I don't want to hear it unless he's serious.
