I was the only girl at his party with 6 of his male friends, what does it mean?

Hey I (26F) have a strong with a guy (27M), we had a brief relationship a year ago and still remained friends. Me and him felt flirty lately, he is single as well I am, be also bought a house and did a small party. He invited me with 6 of his male friends, closest ones. No other girl. But he has girls he was intimate with lately. We did not have anything lately but I'm wondering... What does it mean from him? Does it have any significant meaning? Is it friendzoning or the opposite? I was confident, participated in games, etc. he was warm. And we flirted again. He was not treating me like others though, they all treated me in a special way.

But I'm not sure... Help please

Correcting typo in the first sentence: "I have a story with this guy", not "strong" lol
