<human>: Can you provide a brief rundown of the text in within 3 sentences?

I had a first date last night with a new guy- I'll call him Jason. Jason and I are wonderfully compatible in so many different ways, and the first date went from around 3pm yesterday until 7am today. We talked a lot before our first date, and I really, really like this guy. I see it going somewhere. 

There's one problem: Jason is a smoker. He's not a chain smoker necessarily, but throughout the last 16 hours, he had maybe four or five cigarettes? He would try and put it off for me, but I understand that at some point, he needed a cigarette. 

Not to offend anyone here, but I absolutely despise smoking. The smell is gross, I hate the way it lingers, and I think cigarettes are disgusting. End of story. I'm also super asthmatic and so smoking really bothers my lungs. He knows I hate cigarettes, he told me he wants to quit, but what smoker doesn't say that? I told him I wouldn't get serious with someone who smoked, and he understood. He's still addicted though. 

Before Jason, I always thought smoking was a huge deal breaker. I also know that you can never go into a relationship just expecting someone to change, or give up an addiction. At the same time, he is wonderful in literally every other way.
<bot>: I hate smoking. Had an amazing 16 hour first date with a guy who smokes. He is relationship material, but I can't seriously be in a relationship with someone who smokes. What do I do?
