Moore, however, said she doesn't believe he has anger issues.
"I don't think it's anger, I think it's different," she said. "[My family] know that he's a lot younger than me. He's immature at times. He acts out. He's 29."
Moore added, "I feel like that's where he is. I think he's never been in a relationship this intense and he's really in love, but he's also very immature at times and he acts out."
At the time of the split, Jordan blamed himself and his immaturity for the failed relationship.
