Read on Twitter
let’s start with how they first met. selena and demi first met on the set of Barney & Friends when they were just 7 years old
years later both of them kept busy with their shows on disney channel but still were good friends
they made vlogs or blogs whatever together in 2008 and selena even made an appearance in demi’s show, sony with a chance. also they recorded the song "One and the Same" together
Demi and Selena did a joint spread for People, where they revealed they "do everything together. until 2010, Demi appeared in Girl's Life, where she spoke about her friendship with selena. she said “we're both busy, and I wish the best for her
and “true friends don't let their friends or family be mean to you. If you can't trust somebody, you can't be friends with them."
it’s the same year when fans asked demi how selena was doing and she responded with this;
in 2011 demi entered rehab for the first time for self-harm and selena has been there for her, she was crying on the phone worrying about her. demi said "I was like, look, I should be the one crying, it's all good!' but she was so worried & ever since then we've gotten closer."
everything was okay between them in 2013. both of them showed support on twitter and it’s the same year where demi told MTV they didn’t talk to each other everyday but they were still in each other’s lives
a year later fans noticed that Demi unfollowed Selena on instagram and twitter and later Demi told Andy Cohen, "I think it's just one of those things where people change and people grow apart,"
anyways here’s a video of Demi trying to get Selena dragged
also look at the difference between Selena and Demi through the years
okay let’s get to the point. in 2018 Demi was hospitalized after drug overdose, following the OD Demi unfollowed several people on social media including Selena. According to ET, Demi did so to ‘focus on herself’ and to ‘avoid any difficult relationships’
Selena spoke candidly about Demi’s OD for Elle’s October 2018 Issue. she told them; "all I'm saying is, I reached out personally," she also said “I didn't do a public thing. I didn't want to. I … I love her. I've known her since I was seven. So … it's … that's what I'll say."
everything became kinda shady after Demi hired Scooter Braun as her new manager. if you didn’t know what happend let me explain it to you 
on June 30 of 2019, news broke that Scooter had acquired Scott Borchetta's Big Machine Label Group and, with it, Taylor Swift's catalogue, for over $300 million through his Ithaca Holdings LLC. here’s what taylor posted on her tumblr account:
i also want to mention this. in january 2020 Selena opened about being emotional abused (he also confirmed it) and after being friends for years i’m pretty sure Demi knew about it. in the end of 2019 she was spotted hanging out with Justin and Scooter.
and in March 2020 Demi interviewed Justin on the Ellen Degeneres Show about his album and his struggles
January 2020: Demi made an emotional performance at the Grammys for the first time since her overdose and Selena showed her support on insta tatum. Demi reposed everybody’s support except Selena’s
few days ago Demi did an interview for Harper’s Bazaar and she claimed she and Selena aren’t friends anymore
few hours ago Demi got exposed for having a ‘finsta’ account where she talks shit about Selena
here’s the proof that it was her:
here’s some screenshots about Selena on her account for
Demi’s mother follows the account. after getting exposed Demi erased all of her followers, deleted all posts, changed username, deactivated the account and turned off the comments on her main account
