The self-professed cool nerd was reunited with the nightclub hostess upon leaving the compound on Friday night and - following a little prompting from host Brian Dowling - asked the 28-year-old to be his girlfriend.
"I had a little bit of a love affair with Rebeckah," he recalled earlier in the night. "I miss her... I love her to pieces."
When Dowling asked whether he meant to profess his love for Rebeckah in the compound, Aden replied: "It's such an emotional rollercoaster when you're in there. It's your own little bubble. It's massively intense, your feelings are intensified and it's not like you can go out and get some fresh air."
After teasing that he and Rebeckah were "closer than the cameras may think", Aden confessed: "It was hard when she left 'cause obviously we got so close and I kind of segregated myself from the group. When she left it was awful, it hurt. But it was like a rebirth."
Aden also suggested that the rest of the house felt "threatened" by the 'Wolfpack' he formed with Anton Murphy and Jay Mckray, but seemed to accept the nominations he received from Alex Rose, Louise Cliffe and Tom O'Connell this week.
"[Being nominated] allows you to see other people's point of view, but it's never an easy thing knowing that someone you lived with and got close with has nominated you," he said.
The wannabe psychiatrist further stated that he had never intended to show his emotional side to housemates.
"We all put up a front and I'm the kind of person that doesn't want other people to worry about me," he explained. "But when you're in there, it's hard to get that private space where you can get emotional. So I may have let it out in front of people, which I regret."
As the interview concluded, housemates were treated to Aden's pre-recorded goodbye message, in which he described Anton as his "boy for life" and promised to "smash it out" on a post-show trip to London with Jay.
