Call him at work or at home (changed due to confusion)??

There's this guy I like, and he probably likes me too.

We've hung out maybe 10 times outside of work over the last three years.

If I need to ask him something, I usually call his office. He never seems annoyed, even if I am not at work myself. I also stopped by his office once when I was off and he seemed happy to see me.

Now, in this situation would you be annoyed if the girl called your cell and knew you were off of work? I did this once and he seemed happy to chat, but that was three years ago. He's also answered in situations I wouldn't, like the time when he was in the crawl space under his house trying to fix something.

He gave me his cell # if you're wondering.

Two other questions:

He said to call if I had questions about a class I'm taking (he majored in the subject.) Is that an invitation to call his cell or call him at work?

Should I still be calling him at work for personal stuff anyway? He's the store manager so he can't get in trouble even if I do

Note: I'm not asking if he likes me, how to ask him out, or about workplace relationships. Just about whether I should be calling him at home or at work.

He`ll be more relaxed if you call him at home.
He`ll be able to talk more freely.

Sounds like he`s able to take calls at work too OR maybe he`s being really polite and doesn`t wanna say he can`t accept calls.

He sounds like a lovely bloke who`s very comfortable with himself.

Why don`t you ask him to go out for a drink,cinema etc?

Good luck x

It is more romantic to call at home
