“He also came into my life at a time where I’ve had enough of the narcissistic, cheating and abuse I’ve endured over the years from my previous relationships … " Rose wrote on Instagram.

“I felt so damaged when I met him and pushed him away in the beginning, he has talked me through everything while simultaneously loving me and working with me so I could overcome my fear of loving someone in the most healthiest way again,” she added.

The new relationship came four years after Rose split from rapper Khalifa, 32, with whom she shares Sebastian. In August, she shared a photo of the little boy as he got ready for his first day of first grade.

In late September, she also shared an adorable snap of her son in Los Angeles Dodgers gear after his first win.

“Awww My Pumpkin is getting so big!” she wrote. “He won his first Baseball game today.”

Rose previously opened up to PEOPLE about the mix of emotions that come with motherhood.
