Chris Brown only just recently picked up on the fact that Karrueche Tran wants nothing more to do with him and he seemed to handle it well on Instagram last week, but apparently the singer is super bitter because of his ex.

So last week, Tran and Brown had yet another social media exchange, but it wasn't as volatile as previous exchanges on the Internet between the on-and-off again couple. This one was on Instagram.

Brown seemed to take the high road and wished his ex "nothing but happiness and the best."

That seems to be a bit of a lie though. On Thursday Hollywood Lifereported that the singer is bitter about Tran gaining celebrity status since she dated him.

"Chris learned something from this experience. He learned never to expose the next girl he's with to that Hollywood life and fame," a source shared, adding, "He regrets doing that for Karrueche."

Ouch! It seems like Brown doesn't want "happiness and the best" for his ex based on that tidbit of information.

"He essentially gave her a name and she is only famous for dating him. He provided a platform for her and she's using it to bash him," the source explained of Brown's thoughts about his ex's newfound fame.

He now feels like she just used him to become famous, which many fans of his voiced from the time they initially got together in 2011 up until presently.

"And Kae shows no shame attending every red carpet event in the world, knowing that she's only invited there because she dated him. That irks him and never again will he allow the next woman to use him for fame," the source said.

It sounds like Brown should talk about his unpleasant feelings with a professional before another social media outburst happens.
