You are right about the sentence conveying frustration. The frustration is a result of preceding events.

Thank you for the variation, i like it and i will edit the wording for better flow and clarity.

Your sentence effectively conveys frustration, but the wording could be smoothed out for better flow and clarity. Here’s a possible revision:
"You're avoiding the topic. He's not just a regular fuckboy, you know?"
Comments:

Grammar & Punctuation:

"He is" should be contracted to "he's" for natural speech.
A period after "topic" makes the sentence clearer.


Flow & Readability:

"Not a regular fuck boy" is understandable, but "not just a regular fuckboy" adds emphasis and sounds more natural.


Tone & Style:

If you want it to sound more intense or emotional, you could also try: "Stop avoiding the topic. He’s not just some regular fuckboy, you know?"



Let me know if you’d like another variation!
