Viewers have watched Lillie's relationship with Bear break down on screen, after he confessed to his housemates that he wanted to be single again and that he no longer thinks Lillie is 'the one' for him anymore.
Bear had kissed Chloe as part of a drinking game dare, but then continued to pursue thing physically with her on the show - leaving Lillie feeling "humiliated" and now she wants answers.
Speaking to The Mirror, Lillie explained that she wants to know why Bear has behaved how he has on the Channel 5 reality show.
She said: "How can you do that to someone you care about? If the roles had been reversed, no way in a million years would I have behaved the way he has... If he doesn't want to be with me then that's fine, but why couldn't he have just said that before he went into the house?"
Lillie has previously said that Bear had told her he wanted their romance to work out before he headed into the CBB house. While she revealed they hadn't things official between them, she has stressed they were in a "full-blown relationship" and had been in love.
Lillie added: "Bear told me he loved me after 12 days, and I really believed he loved me. I was certainly in love with him. I saw my future with him."
The Ex On The Beach star's best friend Kayleigh Morris had revealed Bear was planning on buying an engagement ring for Lillie following his CBB appearance, and Lillie admitted that the pair had been talking about marriage and settling down together.
"I saw my future with him," Lillie explained. "I don't know where the person I loved has gone. Everyone is so upset by what Bear has done. His family are upset because they loved us together. As for my family, they will never be able to forgive him."
Lillie's latest comments come after she publicly called out Chloe on Twitter for continuing a romance with Bear, once she had found out about his outside relationship.
Chloe had claimed she had 'no idea' Bear had a girlfriend the first time she kissed him, but given that they continued to get intimate after Bear spoke about Lillie, Lillie tweeted: ""Just watched @itvthismorning - Bear is completely to blame. But to continue a physical relationship after you knew he had a girlfriend who he hadn't broke up with? And show no remorse? #girlcode?"
Chloe, meanwhile, is hoping that she and Bear will pick things up on the outside. She revealed the pair have plans to go away together and talk over their relationship.
She said: "We have plans. He did ask me to wait for him and he said if he went he would wait for me. And he said we'd go away for a few days when he gets out and just talk."
