I think my boyfriend is a little too nice. Opinions on this please?

My boyfriend and I were hanging out and some random number texted him. He asked who it was and some lady sent pictures of herself, which is whatever. But he kept texting her to mess with her and joke about who he was, which is fine. But when she wouldn’t stop texting and kept asking questions, I said that I would text her from his phone “stop texting, leave me alone” he said that’s too mean and he doesn’t want to be rude. Is that not what you’re supposed to do? This just got me thinking if a lady flirted with him in public he’d be too nice or not know how to handle it. He always says if someone ever flirted with him he’d tell them to fuck off and etc. He has a very tough ass mentality and doesn’t really give a shit about other people’s feelings (excluding me usually) So I think it’s a little strange that he said it was mean but am I overreacting?
