A source connected to the couple says they've decided things would be better if they increase their personal space by living under separate roofs. Tyga moved out of Kylie's house last week and into a rental in the Hollywood Hills.
We're told the two felt they were together too much and they were concerned they looked more like a duo than individuals with their own careers. Kylie's recent Australia trip became an issue, as they argued whether she should go solo or with Tyga.
A source close to Kylie says they never officially broke up, but the blow-up made them think -- a little space could go a long way.
