Sofia Richie broke up with Scott Disick because he made his babymama, Kourtney more of a priority

Scott Disick's love for ex-girlfriend Kourtney Kardashian became an issue in his relationship with Sofia Richie.

Scott's split from 21-year-old Sofia was revealed this week after they dated for three years. And it seems there was tension brewing between the couple due Scott's lingering feelings for his ex.

'Scott is always going to be in love with Kourtney, and that’s something Sofia has had to face since even before she got serious with him,' a source told UsWeekly.

'It’s been an ongoing thing. It just became more apparent that his family was more of a priority than she was, and his family would be his main priority over anything and anyone.'

Scott has three children with Kourtney; Mason, 10, Penelope, seven, and Reign, five. They dated for nine years from 2006 to 2015.  

Scott and Sofia, who got together in 2017, are said to have gone their separate ways after Scott's recent stint in rehab, multiple outlets confirmed Wednesday.
