The songstress, 27, admitted it took her some time to heal as she unleashed all of her anger into her song writing for her new album.
Selena got candid about her romance with the superstar and sung about her heartbreak in the album Rare.
She made references to her long-time lover, 25, in Lose You To Love Me, Look At Her Now and Vulnerable – including many others.
The album was released on Friday and Selena’s scathing lyrics have been uncovered.
In the track Vulnerable, she reflected on her and Justin’s rocky on-and-off relationship before he dumped her for his now-wife Hailey Bieber.
Her heartbreaking lyrics read: “If I give you every piece of me, I know that you could drop it / Give you the chance, I know that you could take advantage once you got it / If I open up my heart to you, I know that you could lock it / Throw away the key and keep it there forever in your pocket.”
Selena also addressed her loving attachment to him which in the end left her hanging on to their romance despite their many issues.
“If I show you all my demons, and we dive into the deep end / Would we crash and burn like every time before?” the song lyrics read.
“I would tell you all my secrets, wrap your arms around my weakness / If the only other option’s letting go.”
In People You Know, Selena lashed out at the star for breaking her heart and replacing her with Hailey, 23, just two months after their split.
The lyrics read: “So many wasted nights with you / I still could taste it. I hate it, wish I could take it back ’cause we use to be close / But people can go / From people you know to people you don’t. / And what hurts the most is people can go / From people you know to people you don’t.”
In Crowded Room, Selena talked about their romance at the beginning when the pair were just teens starting out in the showbiz world.
“It started polite, out on thin ice / Till you came over to break it / I threw you a line and you were mine / Yeah, I was afraid, but you made it safe / I guess that is our combination / Said you feel lost, well, so do I,” the lyrics read.
The star has not spoken much about her love-life since the split but admitted she’s open for new love that comes her way.
