Speaking to Digital Spy at the TVChoice Awards last night (September 10), Matthews declared that the Manchester-based PA had made a "mistake" and he has already "moved on".
"I'd like to think I was a gentlemen. I'd never leave anyone at the airport or just lose touch on purpose," he said.
"As my contract had determined for me I had the whole thing on ice [after filming The Bachelor] and unfortunately she went out and pulled Tom Pearce, so I don't think she deserves a second chance."
He continued: "It's not like we had something extremely serious once The Bachelor finished. We spent ten weeks together but I was also dating 23 other girls.
"I was looking forward to getting to know her better and possibly developing what could have been a relationship, but if you're going to do that in the early stages it obviously wouldn't have worked."
Matthews added that he wishes Pearce "all the best" and said "it would be nice to meet him".
The socialite also dropped some hints about Made in Chelsea's upcoming fourth series, claiming that it has the "best opening episode yet", "a lot of emotions flying high" and some "threatening" new arrivals.
