I’m not good with this, could he have been interested in something more but not it’s too late?

A colleague moved from the US to Australia and now is moving back because he misses his parents and brother. At the start we were just friendly “hellos”. 6 weeks ago out of nowhere he complimented me on some work and then started playfully teasing me. He hasn’t stopped since with the complimenting, teasing or trying to me laugh. When in groups, out of everyone he gets along with, he’d come to where I was to talk. He’d never say no to coming out to drinks or dinner and then it would just end up being me and him talking the whole time (like really personal getting to know you) and him glancing looks at me if he was responding to others. He bought my drink one day with the excuse that I drove. When giving me things, our fingers brushed a few times and his knee has brushed my hand whilst driving. Last night we were out with an older colleague, and whilst all talking he was looking at me most of the time. He was insistent on paying but we took the bill instead. I drove him home and we sat outside talking for ages. Then the goodbye started. He started to tell me how I’m the best and he had a look in his eye, deeper than the usual sadness of leaving, I can’t describe it but it was something more. His words were deep, not like a goodbye I’d seen him give others (and it’s been the same words to me the last few days). He also would say, “I’m moving away, why would you be so nice to me you should be angry at me” whereas to others “why aren’t people more annoyed”. He then asked to hug me, it lasted a little longer than it should. My arms were around his neck, his sort of around the middle of my back. Our cheeks touched. We went back to talking, and lots of “I love how you…” when I’d say something. Whilst he was getting out of the car, I passed on a message from a colleague and he came back into the car to talk again. We have each others numbers so we can talk and FaceTime. I know LDR don’t work but could this have eventuated into something more? Am I reading too much into it?

Update: I’ve had some bad experiences in the past with guys who have shown interest, said they’ve like me etc and then I would just get hurt. Those experiences have left me a little confused and hesitant. I do like this guy, but I feel like I can’t really read things anymore so really don’t know how to take things. I also don’t want to say anything because 1. He is leaving soon and 2. If this wouldn’t go further I don’t want to make it awkward and completely lose him

Another update I forgot to add. When he got out of the car, he walked to the door of him apartment complex, turned back around, smiled and waved. The only reason I hadn’t left was because I was still collecting myself after the hug. Again new territory for me as I haven’t had a guy do this before.
