Why would a guy always call you by your first name?

[Anonymous]

I've noticed this particular guy always calls me by my full first name and not shorten it which everybody always automatically does. Always greets me by name whenever he sees me really smiley. Says my name a lot in texts and emails. I have him on instagram also have my name as short version he still always uses the full version. I get the feeling he might like me. Not only from this other reason standing or walking very close beside each other talking etc feel some sort of chemistry. He always notices me I don't always see him but he told me seen me loads.
Does he just like my name or just got me thinking cause he's like the only person who calls me by my full name.

That's odd. For me if someone is calling me by my full name it feels too cold and professional. Makes me feel like people like me only as a coworker, not even as a friend. That's what most people tend to do with me for some reason. But you mentioned that you feel like there's chemistry so I'd focus on that rather than the name thing.

He wants to call you something one else does to signal that he has a different feling towards you than the others. He wants to build rapport. A connection.

He likes you. Oh yeah.
