Why would someone reply with just an emoji?

We hadn't spoke for a few days, so he initiated conversation again, was asking if I'd been on any dates and was flirting/being funny then he just sends a "😂"?

What's that all about?

I guess it depends on your answer, if you have been on dates maybe he's sad

[Asker]

We haven't been on a date yet, he made a rude joke and I said I would have believed him if it wasn't so bad then he just sent the laughing face

When he asked if you had been dating, what was your response

[Asker]

I said that I've been asked but it depends if they spark my interest, but I haven't been on a date

I don't know, he just sounds like an asshole to me
