Are we just friends or are we more than that??

Alright here is my situation
About 1,5 month ago I started a new job, as a corona test person, that my friend got me. She told me there was this fun guy working there and she thought we could make him put us in the same tent. I show up at work and true, there is a fun handsome guy working there. I actually remember meeting him at a party about 10 years ago when we were 15. Anyways, he has a girlfriend, that lives abroad, but is going to move in with him in the coming weeks. We have a lot of fun at work, and I dont feel like we flirt at all but just have really good chemistry. We live not so far from each other so we end walking home together after work. He just started university (i am in my 4th year) now but we are the same age. I remember really liking him but did not think anything romantic, since I knew he had a girlfriend.
About a week later, saturday evening, he suddenly texts me out of the blue if I want to grab a kebab. I had been on a boring tinder date during the day, so I thought sure why not. We end up going to his place (because everything closes at 10PM) and talks for hours. He ends up walking me home, and when we says goodbye he says he can feel I am dangerous to him… The following week we hang out a few times watching movies etc. but just af friends. We didn’t talk about what we were doing, but I remember thinking this is so strange, I dont think we are going to do this when your girlfriend moves in.
Anyways a few days later they break up and she is not coming. We have hung out a few times since, and still nothing has happended. But he tells me he loves to hear me talk and that I stylish and unique. I have started to catch a little bit of feelings but I so confused why he hasnt kissed me yet.
I try to akt friendly because I dont know what our situation is. Its been 4 days since we last hung out. He sends me snapschat every day but doesnt text so often.
Last time we hung out I really thought it was going to happen but it didnt… I kind of sensed that we wanted to ask me what we are doing but pulled his question back. Then he said I was his best friend… (We have known eachother for 1 month)
I am confused and I feel vulnerable now. I dont know what to do?
I dont think I can continue being friends like this if we dont get more romantically involed..
