Rihanna allegedly has doubts about Chris Brown's ability to be faithful.
The pop star is reportedly worried that singer Chris could cheat on her. This comes after Chris allegedly met up with his ex-girlfriend Karrueche Tran to tie up loose ends after their recent split.
"His game playing is so confusing for Ri," a friend told British magazine Grazia.
"She simply doesn't understand why he needed to see Karrueche."
According to some of Rihanna's friends her relationship with the bad boy rapper has left her with serious psychological scars. Understandably, the star is struggling to trust Chris now they are reportedly back together, given their on-off history.
"When Chris is messing her around she loses all interest in normal life," the friend continued.
"She doesn't look after herself and she acts out. She's always on edge, texting Chris constantly - it's like there's no one else in the world who she'll listen to."
Rihanna and Chris are thought to have rekindled their romance after being spotted together in public several times recently.
The pair split in 2009, after he violently assaulted her.
