Is this making a move

Ok so me and a guy friend I work with who I very much just see as a friend and that’s all we went out drinking with work and everyone went home but us two who wanted to stay out abit longer

So we went to a club had a good time nothing weird then he insisted I went back to his flat to wait for my 8am bus so I wasn’t wandering the town for a cab alone so I was like okay fair enough

But when I sat down he sat right next to me and then said “come here” and pulled me into his chest and had his arm wrapped around me

I freaked and panicked lol and like said I wanted to go home

And he kept saying “no stay abit longer you don’t have to go now”

But I insisted and I left

Now we’re at work together and i just feel so so awkward

He has a girlfriend !!!

I can’t deal with this type of situation if he was making a move - I’m unsure like what if he was just trying to be nice ?? Idk help 😂
