Maria Shriver is telling friends she's now unsure if she wants to divorce Arnold Schwarzenegger ... TMZ has learned.

We're told Maria is torn, partly because of her strong religious beliefs that do not include divorce.

Making matters even more complicated -- we're told Arnold still desperately wants Maria back, and has been "extremely sweet" to her and has made numerous gestures -- which include presents -- to win Maria back.

Maria filed for divorce on July 1, though she moved out months earlier. She's already bought a mansion in Brentwood, CA, which she's in the process of renovating.

Sinead O'Connor abruptly ended her marriage to her fourth husband Barry Herridge ... after just 16 days.

The couple wed on December 8 -- the Irish singer's 45th birthday.

The news was announced on Sinead's website. "He is a wonderful man. I love him very much. I'm sorry I'm not a more regular woman," she posted. "I truly believe though it is painful to admit, we made a mistake rushing into getting married, for altruistic reasons, and weren't aware or prepared for the consequences on my husband's life and the lives of those close to him. He has been terribly unhappy and I have therefore ended the marriage. I think he is too nice to do so. And too nice to trap."
