Discussing his controversial decision to walk away from the show, Richie told 10 Daily: "When I decided to leave, that was really, really heavy for me."
The shocking TV break up was a "learning experience" for Rich.
But his ex Alex Nation thinks he still has a long way to go.
Telling Cass in a surprise moment of comfort, Alex said, "What you're going through and the confusion and everything, I went through the same thing with him."
"He's a good person, but I think he's a really lost one. He's scared that he would hurt you and I feel like he means that, but he's scared of committing to something as well."
"He's got a lot of growing to do within himself, and it's not you - it's not you."
Reflecting on his time, Riche confessed, "The first three to four days in Paradise I wasn't myself, I was still there it was just emotionally very difficult to handle. After that I sprang into action and became myself."
"I was a lot happier, jovial and having a lot of fun with everyone."
The reason why he dumped Cass - he just didn't think they'd work.
