According to TMZ, Ortiz is expected to move back into the couple's home this week. The mixed martial arts fighter was arrested last Monday on charges of felony domestic violence.
Upon his release from jail, Ortiz claimed that the incident was prompted by a confrontation over Jameson's addiction to prescription drugs. Jameson denied the drug claims and alleged that Ortiz threw her into a bathtub, injuring her shoulder.
Both withdrew the allegations against each other last week.
Sources say the couple would have reconciled earlier, but they were waiting for the automatic restraining order that prohibits Ortiz from having contact with Jameson to expire.
The unmarried couple have two sons together.
