So I said yes to his invite for drinks with his coworkers. That was the last time I saw him in person so we only interacted online afterwards.
As I said, he sent me a message right after coffee that it was nice to meet me. I replied that it was nice to meet him too.
Last week and this week we exchanged a few messages but it was only about work. He also messaged me to apologize that it took him longer to finish one task I was waiting for but again, it was just about work. His messages are friendly, with lots of emojis.
I work for a big company and we can also work from home so I have no idea when I'll see him next at the office.
I don't think I was cold during that coffee break, we talked very easily, there were no awkward pauses. It's hard for me to tell if I was flirty because I'm not sure if he would interpret it as flirting, but he did laugh at my jokes. I tend to be a little shy but overall the coffee break went really well, at least for me.
