Guy acts different when we’re alone?

Anonymous
Gotten close with this guy at work over the last few months and we’ve hung out a few times outside of work (usually with others, but once we hung out alone). That day we were alone I got a different side of him - he seemed more comfortable, goofy, and silly and we had some good conversations throughout the day. When we were going to meet up with another friend of ours, he acted like he didn’t want her around even though they get along fine.

It’s weird bc time and time again especially since this day, I’ve noticed that when we’re around people he doesn’t act as much like this, but when we’re alone at work and separate from other people, he goes back to this behavior and we mesh really well together and it feels right. Other times we clash and end up in little arguments for weird reasons. He’s definitely not a player, and he’s said I’m one of his closest friends. He got out of a long-term relationship not long ago and said he wanted to be good friends with the girl he’s in a next relationship with (like courting).

He knew I liked him from when we first met bc he asked my friend, but when she asked him if he liked me, he never answered - just smiled and walked away. However, she asked if he liked me about a month ago and he said no.

Anyway, I’m curious why he acts so different when he’s around me if there’s no feelings. I’ve thought maybe he doesn’t want others to think he does, but if he values me so much as a friend as he’s said, why keep dragging me along knowing I’m trying to get over him?

Examples are him smiling and laughing A LOT more, joking around and teasing me incessantly, I catch him looking at me a good bit when he thinks I’m not looking, he stands pretty close to me, brushes our arms/hands together occasionally, etc. He also talks about me a lot with my friend even when I’m not involved in the topic. Like I will always get brought up somehow even if I’m not there. This whole thing has me so confused.

Also, he doesn’t act like this with others girls that I’ve noticed - just me.

He had plenty of chances to make a move on me that day we were alone together so I know it’s not just a physical thing or sex he wants.
