Oct. 19 (UPI) -- Christina El Moussa has reportedly split from boyfriend Doug Spedding.
The 34-year-old Flip or Flop star broke up with Spedding amid reports he is seeking treatment for drug addiction issues, according to E! News.
"Christina supports Doug's decision to seek treatment and remains in contact to support his recovery," a source said.
Another insider said El Moussa's friends encouraged her to split from Spedding after his alleged issues worsened this month. The reality star ended the relationship in part to protect her children, daughter Taylor and son Brayden.
"Doug has had a huge history of drug and alcohol abuse and Christina was warned when they first started dating," the source said. "It has gotten pretty bad this past month and Christina's friends urged her to end the relationship."
"She absolutely has no tolerance for any substance abuse, especially around her kids," the person added. "She is disappointed and really liked Doug but knows this is for the best."
InTouch reported Wednesday that Spedding has entered an in-patient rehab facility for "addiction issues." El Moussa reportedly urged Spedding to check into the center because "she just wanted to help."
"Christina is the type of person who sees the best side of others, and that's how she was with Doug. Caring about someone does not save someone and Christina knows that," an insider said.
El Moussa was first linked to Spedding in July following her split from husband and Flip or Flop co-star Tarek El Moussa. She and Tarek announced their intent to divorce in December, but will continue to co-star on the HGTV series.
