Brown now wants Tran to buy a house so she can start a new life for herself, The Sun reports.
"Neither Rihanna nor Chris want to make things harder for her than they already are," a source said.
"Chris wants to set her up financially and do right by her - he wants her to stay in his life if possible.
"Rihanna called Karrueche for a proper heart-to-heart. They needed to air a few problems.
"The girls talked for close to two hours. Rih answered all of the questions and Karrueche had a few home truths to tell her."
It was previously rumoured that Brown wanted Tran back and was constantly texting and calling her following their split.
