2-in-2-1 Discussion Forums - Prayers and advice needed Please

I really do not know where to begin. I met and married my wife believing that she was a Christian. She has behaved so badly and with total dis-regard for the teachings of the Bible. She is an only child and has a very domineering mother who is a non believer. Her mother treats her father in a terrible manner and has no respect for this placid and loyal gentleman. Instead of my wife treating our marriage as a Christian one she tries to replicate the one that she had learnt from her childhood. She has Committed Adultery, told Lies Under Oath, been violent to me and our children on many occasions and many many other hurtfull and damaging things. She has never said sorry os expressed any remorse for anything, often blaming others for her behaviour. The last time she beat me up and took a piece of wood to me, I tried to get her to appoligise for her behaviour and after asking several times, five hours later in desperation to get her to see that there is no exscuse for violence I called the Police. Since then she has only resented me for this, and a few months on still has not said sorry. I truly Love her and I do understand that she has been damaged by her mother, but Christ can heal those things if she would only let him in. I am not feeling able to cope with the constant struggle and dis-harmony for much longer, I have had other things to cope with this last two years including Berevement. God has helped me along this path a lot, but sometimes I despair and even doubt my faith in Him. My wife and I have been Blessed with three Wonderfull children but they are getting old enough to be shaped by her in ways that are not the ways that they need to. I want the Joy, Peace and Harmony that Christ wants to give our Marriage. Please find some time if you can to Pray for my wife and I and our children. Yours Sincerely in Christ. Brian
