Should I be a bitch?

I recently posted about a guy I’m talking to who gave my coworker a note saying “call me ...” with his actual number and then told me it was a joke, didn’t clear up anything to her. He came back to my store with some flowers, I was in the back. He STILL came in joking about it and said they were for her. She said, “no they’re not” & he laughed then said “nah, it’s for Grace.” She called out to me in the back but I refused to come out. When he left, I grabbed the flowers and threw them in the trash. I’m officially done with his bs & idk if I should send him this
