Rihanna reportedly feels let down by Chris Brown's behaviour, not least because she took a "massive risk" letting him back in her life.
The pair have been embroiled in an on/off relationship for several months, with Chris seemingly confirmed they have split for good last week. He told interviewers that while he still felt a great deal of love for Rihanna, 25, he is too young to consider "wife-ing" anybody.
Rihanna is said to be feeling let down by her beau, especially after the reunion caused a massive backlash because of Chris' assault against her in 2009.
"Rihanna took a massive risk with Chris, letting him back into her life after his conviction, learning to trust him again, then going public with their romance again," an insider told British magazine Star.
"She took more than her share of flack for staying with a man who beat her, and all the while Chris has been reviving his career. He was virtually blacklisted by the industry after what he did, and with Ri's support - and their publicity their relationship has brought - found respectability.
"Rihanna is angry that she let herself invest so much time in Chris again and is sick of him constantly letting her down. She feels like he takes her for granted and forgets what they've been through and what she's done for him - she basically put him back on the map."
Rihanna and Chris certainly haven't held back with the feelings, and were vocal about the situation on Twitter of late. "Settling is not an option! Nothing less than 100% loyalty, honesty, and respect!! Love ain't for kidz #butimsleeptho (sic)" Rihanna fumed.
Chris tweeted: "Sometime loving someone is too much! So loving from a distance will help everyone grow! Be blessed. Live ya life! (sic)"
