Lillie and Gaz had split in November last year, but recently reunited on Ex On The Beach's fifth series. Lillie had surprised Gaz on the show to get closure from their break up, but while in the villa, she soon found out Gaz had actually cheated on her while they were dating.
She was forced to live with two girls Gaz had slept with behind her back, and surviving the experience, Lillie has reflected on the effect Gaz's infidelity has had on her.
In a new video shared by MTV, Lillie admitted: "After everything with Gary, yes, he has definitely made me nervous about getting into relationships and getting to know guys."
Gaz had confessed to sleeping with Chrysten Zenoni during a trip to Australia while dating Lillie, and it also came out that he'd had sex with Melissa Reeves early on into his and Lillie's relationship.
Not surprisingly, Lillie broke down on hearing about both occasions and said she felt like the two years she had dated Gary were all a lie.
In the series finale of Ex On The Beach, fans saw Gaz clear the air with Lillie once and for all, and apologise for being unfaithful. He told her: "A lot of stuff has gone on here with the whole Chrysten and Mel and the fact that I cheated on you. The other night when you were crying in my arms and we went to bed together, I hope that does prove that I still do care about you.
"I'm sorry, I am so sorry I cheated on you. I will always care about you a lot. We had some of the best times ever and I'm sorry that the things that came out, came out in here. I f**ked up a few times, I've been caught out and I'm sorry about that. The rest of our relationship was real."
Lillie, meanwhile, said: "I came here to get closure with Gary. It hasn't been the easiest journey, but I'm going to be going home a much stronger person than when I came in here."
Viewers then saw Lillie pick up her romance with Bear on the show.
They had got together following Lillie's arrival to the villa, but their romance broke down after Bear was caught kissing Chrysten behind Lillie's back. While it may have been a case of déjà vu for Lillie, she didn't hold a grudge and was happy to rekindle things with Bear on the last day in the villa.
He told her he "missed her" and wanted to spend the night with her and no one else. Seeming keen to do so, Lillie told Bear: "You're lucky you are pretty."
Although, she insisted she wasn't thinking long-term when it came to her co-star.
Lillie added: "Bear has a bit of a reputation, but right now I'm not thinking about a massive relationship and future. I'm just in the moment and having fun."
Lillie and Bear did go on to date following filming for Ex On The Beach, though, but publicly split while Bear was in the Celebrity Big Brother house.
He had starred on the show in August, several months after getting together with Lillie, but viewers saw him kiss his housemate Chloe Khan as part of a drinking game, before then announcing to his housemates that he wanted to be single.
Bear said he "didn't have time" for a girlfriend anymore and no longer thought Lillie was The One for him. He continued to pursue things with Chloe and was later forced to face Lillie, as she confronted him in the house. Lillie told Bear he had "embarrassed" and "humiliated" her.
Since then, and having watched Ex On The Beach back, Lillie has said she has had the "shock of her life" seeing what Bear was *really* like on the show.
He had told Chrysten he wanted her to be his "little secret" and moaned to the camera about Lillie "not putting out."
Lillie told MTV Australia: "I don't think people realise I didn't know anything of what Bear was doing until I watched it myself on TV. When I was told about Chrysten, I thought they maybe had a kiss at some point. I didn't know it had been a bit of a secret affair and still didn't know until I watched it for myself last week.
"Obviously for me, I only saw what Bear was being around me, when he was always lovely and funny. I didn't hear what he was saying when it was just him and the camera and the way he was really being. I honestly had no idea about that... Let's just say I'm glad we are no longer together."
