"Kim spent a lot of time with Reggie at his house, and the two had very long and thoughtful conversations about what their future could look like together," relays a spy. "Kim absolutely wanted to get back together with him, but Reggie pointed out that they both want very different things out of life. Reggie is much more low key than Kim and does not want to live his life in the public eye the way she has chosen to."
Continues the mole, "Remember, when Reggie and Kim first started dating, she didn't have a reality show -- that came about a year into the relationship. There will always be a lot of love between Kim and Reggie, but he just doesn't see a future with her."
The NFL player was also apparently worried about Kardashian's timing.
"Yes, Kim is no longer is with Kris and the divorce will become final soon, but it hasn't even been a year since the wedding," explains the source. "Reggie felt that getting back together with her would be a step backwards for him and he moved on a very long time ago."
"Reggie doesn't have any bad feelings towards Kim, and he only wants the best for her," concludes the insider. "But he told her she should spend some time on her own for a while. Several weeks after he had that conversation with her, she went public with Kanye, affirming that he made the right decision."
