Guys, when a guy acts a bit friendly/flirty in person but ignores your dm on social media, does it mean he’s not interested?

There’s a guy who my brothers fiancé and my friends think was trying to flirt with me at a party but when I sent him a message later, he left me on delivered. However, he’s seen my stories so I know he’s been active. Does that mean he’s not interested?

I guess he opened it and just didn’t respond but either way🤷🏻‍♀️
