Tasha Smith says she agrees with her husband that someone in their house has reason to fear murder ... but she says it's her.
The "Why Did I Get Married?" star just filed legal docs, claiming hubby Keith Douglas flies into jealous rages, calling her a "f***ing d**e" and accusing her of sleeping with other women. She says, "When he's in a rage, I feel that he is capable of killing me."
We broke the story ... Douglas has similar concerns, saying Smith flies into booze-fueled rages and threatens to kill him, warning him to "not fall asleep or something will happen."
Douglas got a restraining order last week, requiring Smith to stay an absurd 2 yards away from him while they're in the house together ... but we're told Douglas has since moved out.
Smith says she'll call a bunch of celebs in their divorce case to validate her claims of abuse, including Tisha Campbell Martin and Elizabeth Rohm.
Smith says in her docs she's friends with Michael Jace -- "The Shield" actor who allegedly shot and killed his wife -- and says she told her husband she was worried she'd end up like Jace's wife.
Both deny the allegations the others have made. Fortunately, they didn't have kids together.
