Story highlights Sinead O'Connor announced on her website that she is ending her marriage

She blames pressures placed upon Herridge by "certain people in his life"

"I'm sorry I'm not a more regular woman," she writes

Sixteen days after her December 8 Las Vegas wedding to boyfriend Barry Herridge, Sinead O'Connor is ending the marriage, the "Nothing Compares 2 U" singer announced Monday on her website.

"Dear friends," O'Connor 45, writes, "I had for reasons u will all understand, wished to keep this private but have been told today it is to be leaked in the next few days despite my best efforts. So I must now leak it myself so as the record is straight."

She blames pressures placed upon him by "certain people in his life" not to be with her based on press reports about her.

"Within 3 hours of the ceremony being over the marriage was kyboshed by the behaviour of certain people in my husband's life. And also by a bit of a wild ride i took us on looking for a bit of a smoke of weed for me wedding night as I don't drink," she writes. "My husband was enormously wounded and very badly effected by that experience and also by the attitude of those close to him toward our marriage. It became apparent to me that if he were to stay with me he would be losing too much to bear."

She adds, "A woman wants to be a joy to her husband. So.. U love someone? Set them free."

She also says, "He is a wonderful man. I love him very much. I'm sorry I'm not a more regular woman. 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."
