<human>: They've been together for 3 years and it's been generally good, though the rough patches they do have are *really* rough. He's not abusive, just an a-hole sometimes. But he's a big fan of the grand gesture and that's how he plans to propose. For anonymity's sake I don't want to get too specific, but what he's planning is on par with proposing through the jumbo-tron at a basketball game. My concerns are 1) that she'll say no, and 2) that she'll *want* to say no, but will say yes because it's such a public proposal. Should I advise him to tone it down, or should I just be ready to be there for him if it doesn't go his way?

Can you provide a brief rundown of the text in within 3 sentences?
<bot>: He's going to propose in front of a lot of people and I'm not sure she'll say yes, and if she does she might not mean it. Advice?
