Gia Allemand's death came as a surprise to many, when she took her own life last week.

Sources reveal in the new issue of Us Weekly that she was struggling with many demons. In addition, her rocky romance with boyfriend Ryan Anderson, an NBA player with the New Orleans Pelicans, may have been her breaking point.

One insider says the couple of two-and-a-half years clashed over their disparate visions of the future. Allemand, 29 at the time of her death, wanted to get married and have a family, the source tells Us, but Anderson, 25, "wasn't ready to commit."

"He started breakup talks," the source says of the athlete. "They were fighting a lot."

"She had such an amazing impact on my life and anyone that knew her was blessed," he continued. "All I have left is to cherish those memories we made together and help perpetuate the many values, faith, and love that we shared."
