"Christina went to put an alarm on Doug's cell phone to wake him up and she saw text messages [between Doug and his ex]," a source told the outlet.

Despite reportedly cheating on her, El Moussa is making a concerted effort to support Spedding as he seeks to get help for his alleged drug abuse.

"Christina encouraged him to go back to rehab," the InTouch source continued. "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. She just wanted to help him."

On Tuesday, El Moussa shared a cryptic Instagram post that seemed to allude to the recent tumult in her life.

"There is no shame in beginning again," it read. "For you get a chance to build bigger + better than before. People can impact you in different ways ... the important ones enter your life for a reason a season of a lifetime."
