Los Angeles ( CNN ) -- Camille Grammer accuses her ex-boyfriend of leaving her bruised and battered from a fight while she was recovering from cancer surgery . A judge granted the ex-wife of actor Kelsey Grammer a temporary restraining order Tuesday that says Dimitri Charalambopoulos must stay at least 100 yards away from her . CNN has been unable to reach Charalambopoulos for a response . Court documents filed by Grammer -- a former `` Real Housewife of Beverly Hills '' cast member -- describe in dramatic detail an early morning fight with Charalambopoulos in a Houston , Texas , hotel where she was recovering from surgery two weeks ago . `` I wake up at least twice per night with visions of his face as he was attacking me , '' Grammer said in her filing . `` I continue to fear for my safety and for the safety of my children , who had grown to trust Mr. Charalambopoulos during the course of my relationship with him . '' Grammer , 45 , began dating Charalambopoulos , a 36-year-old fitness trainer from Texas , more than two years ago , according to court papers . Her divorce from Kelsey Grammer was finalized in February 2011 . The argument began at 1:30 a.m. on October 16 when she was awakened by the vibration of Charalambopoulos ' cell phone `` with incoming text messages and phone calls from another woman , '' Grammer said . `` Inquiry escalated to argument , and Mr. Charalambopoulos became verbally abusive to me , shouting expletives and insulting me with misogynic epithets , '' she said . `` He grabbed me by the hair , twisted it around his hand , and repeatedly pulled my head into the bed and its headboard . In so doing , Mr. Charalambopoulos succeeded in pulling out swaths of my hair and gave me a large , painful contusion on the side of my head . '' When Grammer began screaming for help , `` Charalambopoulos squeezed my nose between his fingers and pushed upward forcefully , meanwhile covering my mouth in an attempt to silence me and to prevent me from breathing , '' she said . `` I experienced great pain in my nose and became afraid for my life as a consequence . '' The attack continued for another 40 minutes to an hour , she said . `` I begged him to stop and threatened to call police , '' she said . `` He wrestled me on the hotel bed , repeatedly slamming my head and face into the furniture , and eventually he succeeded in completely immobilizing me . '' Sitting on top of her -- with his knees `` mere inches from the area that had been the object my invasive surgery only a few days before '' -- Charalambopoulos put his fist in her face and told her , `` I wan na smash your head in , '' and `` I 'll give you a reason to call the cops , '' Grammer said in her sworn statement . Before leaving her hotel room , he smashed her iPhone and unplugged and disassembled the hotel phones , she said . `` He told me I was going to hell , and then , to make his escape , he said he would 'knock ( me ) out ' if I moved from the bed while he left the hotel , '' Grammer said . Three minutes after he walked out , Grammer `` hobbled down '' four flights of stairs to the hotel lobby where an employee called police , she said . A Houston police spokesman said no charges have been filed , but the incident is still under investigation . He noted that `` they broke each other 's cell phones '' and her injuries were minor . Grammer 's request for the restraining order included photographs of bruises on her wrists and face , her broken cell phone and a clump of her hair . A hearing to decide whether the temporary order will be made permanent is set for November 19 at the Santa Monica branch of the Los Angeles County Superior Court .
