Is it just me or is this boy flirting with me 🤔

I have a co-worker names Trey at my job and on occasion he’ll argue with me, or get really close to me like he’s gonna do something and it would obviously get me really confused considering the fact that he has a girlfriend! Oh yeah, I’m dealing with one of those guys ladies. On countless of times he’s given me hugs (but only in private) and i would go tell my girl co-workers and they would say “he’s totally flirting with you” and I’d believe it (cause I can’t tell when a guy has interest in me) we’ll just yesterday, Trey would not stop bothering me about getting a hug (when I was putting the broom away in the back, he wouldn’t let me leave until I gave him one) so he took me by the bathrooms and gave me a pretty intimate hug. My arms were around his neck and his hands were a little to close to my ass and He squeezed me and picked me up a little. He leaves I go back and tell my guy co-workers and they all say “Trey’s a friendly guy (which was wrong) it was just a hug so chill out” AND NO MATTER HOW MANY TIMES I TRIED TO EXPLAIN THE BUILD UP THEY KEPT SAYIN IT WAS A DAMN HUG!!! What’s the final verdict guys cause I am not okay 😫😫
