Kid Cudi wants his former girlfriends to know he's sorry. 

The rapper/actor took to Twitter on Saturday, to reflect on his personal growth and the lessons he's learned along the way. Cudi began by explaining the importance of self-love when it comes to romantic relationships: "U can't be in love w someone until u love yourself," he wrote. "It took me years to learn that."

Cudder then acknowledged that he wasn't always the best boyfriend, especially in his 20s and and early 30s. He then apologized to all his past partners, and took full responsibility for the failed relationships, blaming mistreatment on his part.

"I apologize to all my girlfriends in my 20s and early 30s I let down and treated like shit because I wasnt right," he tweeted. "All of my relationships didnt work out because of me. I had to accept that and find peace and be better."

Cudi's mental health struggles have been well-documented over the years. He checked into rehab in 2016, citing "depression and suicidal urges." Cudi opened up about this dark time in his life during a 2018 interview on Red Table Talk with Jada Pinkett and Willow Smith.

"It's like my life was this show and I was always supposed to be on, but when the show was over I was completely miserable for a long time," he explained. "I was not happy when I woke up in the morning, it started off with something as simple as that. Just being like 'Why don’t I feel OK?' and not really knowing what that was."

Cudi says he's in a much better place today, and has learned to love himself again. On Saturday, he also shared a few words of encouragement to those who are struggling: "I've fallin back in love w Scott. It feels great!" he tweeted. "To anyone whos still dealin w things, know that u will be ok and u will find a way to the light. I thought id never find a way out of my madness. So silly of me."
