Karrueche Tran and Chris Brown were posting loving pictures of one another on Instagram just days ago, but it seems they have broken up once again. Tran stayed with Brown while he was in jail for 108 days for violating the terms of his probation related to his assault on Rihanna in 2009.

Just last month, Tran had a welcome-home party for him when he was released from prison, but that was not enough to keep the unstable pair together.

Now, two days after spending July 4th together, both have deleted all pictures of one another on Instagram. While it is unclear why they split, the last time they broke up, in March, TMZ reported it was because Brown refused to stop contacting other women. That is rumored to be the reason why Rihanna and Brown fought and consequently broke up in 2009.

In addition to deleting pictures, Tran posted cryptic messages on her account in the past two days, which may hint at why they broke up. “Love what you have before life teaches you to love what you lost,” she wrote in one post.

On Sunday, she posted another message, which may have indicated her relationship with Brown was over. “In the end, only three things matter: how much you loved, how gently you lived, and how gracefully you let go of things not meant for you.-Buddha.”

Tran and Brown have had quite a troublesome few years and, in 2012, the singer admitted that he loves both Rihanna, his ex, and Tran.

“I’m stressed out … when you share history with somebody, then you tend to fall in love with somebody else, it’s kinda difficult [sic]. Is there such thing as loving two people? I don’t know if that’s possible, but for me, I feel like that,” Brown said in a video. Considering the two have broken up a number of times, it remains to be seen if they will get back together soon.
