Is he messing with me or being a creep?

Helloeriss01
This guy has had convos with me before where’s he’s been awkward. He’s complimented the way I smelled and once I told him I was looking for him and he was like “we’re you?” Kind of flirtatiously. He’s nice and has a girlfriend and he’s ten years older than I am.
There’s this girl at my job and and we’re the same age and we talk a lot because we relate on that.
I do the guy favors and print something out for him sometimes. He’ll tell me “thank you” and and stare at me for longer. I’ve also caught him sneaking glances. I’ve been told by a lot of other people that I’m pretty. He once messed my name up on purpose to mess with me when he knew my name and tried to scare me once over a bug.
With the other girl he’s weird but I assume I’m in my head because I’m known to overthink.
She has been doing the favors for him on some days because he splits it up and she has to forward the emails that he sends to her to my account because she can’t login on hers yet.
So she forwarded one of the emails he sent to her today and I read it and it said “you’re the absolute best 😊” with the blushing emoji at the end.
I asked someone and she didn’t think it was flirtatious at all and just said it’s just appreciation. Also the girl my age and I talk a lot so I feel like she would have said something.
The other day, he told me good morning and asked how I was and I brushed him off and I think he sensed it and kept coming near me and trying to join my convos and looked at me.
Friday he asked me if I did something and I told him I would do it later then we looked at each other and he was like “ok” then it got awkward and he left.
Yesterday I was talking to the girl and he came when it was time for me to leave and looked at me and was like “I realize I never say bye to you Ashley. So just wanted to say bye” and kinda rushed me out. But I feel like he wanted to just talk to my coworker because I heard them talking after I left or maybe mess with me? Was he messing with me?
Is he messing with me or being a creep?
