Sources close to Oksana tell us right after the alleged Jan. 6 attack, Oksana broke off her relationship with Mel for about 3 weeks.
But then she went back ... and was overtly affectionate with Mel in various ways. Oksana is telling friends, Mel tearfully convinced her the alleged attack was a one-time-only incident and that he would go into therapy to get better.
And there's this ... sources connected with Oksana now tell TMZ ... her "close" relationship with her bodyguard -- convicted felon Kristian Otto Herzog -- is further evidence she's drawn to men who have violent tendencies.
But there's more with Mel ... Oksana says she was a closet girlfriend until the January 6 incident. Then afterwards, Mel promised he'd treat her like a trophy girlfriend, taking her out in public -- like the Golden Globe event -- and publicly bragging about their relationship.
