AIO for not calling the girl I’m seeing during my lunch break?

We’ve been dating for 1.5 months and more casual (seeing other people) for two weeks as she wanted to explore her options and make sure she was picking the right guy.

Today she calls me at work (Ive let her know multiple times to only text me at work as I’m constantly on calls with coworkers around the country) and then texts me the above when I don’t pick up.

I guess the guy she went on a date with recently had called today on his break and she decided to politely inquire as to why I didn’t do the same.
