It's the relationship that will never end.

Yes, Chris Brown and Karrueche Tran are by no means happily together. But despite their single status, the pair just can't seem to avoid talking about each other. Need an example? Here's what went down this weekend. 

It all started when the rapper discovered his ex spoke out about their relationship in a recent interview. Instead of remaining quiet, the "Run It" rapper reportedly sounded off on Instagram.

"Honestly, it's so f--king pointless to keep doing interviews about me. Talk about your career," he wrote. "If there is no more relationship then u shouldn't be doing f--king interviews with people I won't let get the pleasure of prying into my personal life. S--t starting to get real weak now."

Lo and behold, Tran saw the Instagram comment and decided to explain herself on her own social media page.

"They asked a question and as a mature adult I answered. I'm not gonna shy away from something that I lived through," she explained. "I'm not speaking on you or bashing you (like I easily could). Don't be mad at me because our relationship is over due to your lack of loyalty."

Oh yes, she went there.

"You know what's weak?? You forcing yourself into my car..my broken window..blowing up my phone..trying to shower me w/ gifts," she continued. "Man the f--k up and change the bs in your life like I've told you several times."

In a surprise turn of events, however, Brown didn't respond with anger and more accusations. Instead, he decided to explain his love for the recent Daytime Emmy winner.

"I'm eternally thankful for you being in a part of my life. I've learned so much from you," the 26-year-old wrote on Instagram with a throwback picture of the two in happier times. "I wish u nothing but happiness and the best."

He added, "@karrueche all I was doing was trying to fight for the woman I love. Thanx I learned a lot."

Something tells us this isn't the end of this roller coaster of a relationship.
