The reality stars dated during the ITV programme's first two series, but split in July after Norcross decided that he "no longer felt committed" to the relationship.
Pope revealed that she has now abandoned all attempts to maintain an amicable relationship with the nightclub owner, as she finds him too "immature" to be around.
"I try to be friends with Kirk but he is very immature," she told New. "He wouldn't let me see my dog so I don't want to be his friend.
"Any mature grown-up would understand that even if you break up with someone then you still let them see their dog that I bought and looked after."
Pope also said that she was grateful to have TOWIE co-star Lauren Goodger, who helped her deal with the break-up amid her own separation from fiancé Mark Wright in August.
"Both of us were in a bad way," Pope recalled. "But she was very good and got me up, got me out, got me partying and I think it's exactly what we needed - two girls just out on the town not worrying about men anymore."
Neither Pope nor Norcross is expected to appear in the next series of TOWIE, as she is reported to have been axed and he will apparently appear in Channel 5 dating series The Bachelor.
