Kylie Jenner wants to "erase" Tyga from her memory.
The 'Keeping Up With The Kardashians' star is reportedly "absolutely fuming" at her ex-boyfriend and is said to be so upset that she is trying to act like he never even existed.
A source told PEOPLE magazine: "She's absolutely fuming. She's caught him lying and talking to other girls behind her back before, and this was the last straw.
"She feels super betrayed and is just so p***ed off, damaged and hurt about it. She plans to erase him from her memory and act like he never even existed in the first place."
Meanwhile, the 26-year-old rapper is also said to be "devastated" that the pair have decided to go their separate ways but is "not giving up" on their romance.
Another insider shared: "They are on a break. They were just a week or so ago talking about 'ever after' and things got messy this past week.
"Kylie wants time to just be by her self and do her. Tyga is not giving up as that's his one and only lady."
The pair - who had been dating for over a year - reportedly ended their relationship on Tyga's birthday on Thursday (19.11.15)
