advice

This is my first post, so please understnd if I leave out facts. Last Nov. my wife of 24yrs. got up and left for three weeks. She came back a week before christmas and announced the "I love you, but...." you all know the rest. I begged her to stay for christmas. she did, big mistake!! She stayed out most nights and got drunk. My wife drank giner-ale at our wedding. My three children (20, 21, 23)were home looking at me for answers, I had none. I talked to mental heath people before New Years and they explained what a MLC was, and that I had too support her and be understanding. They also warned me of all the things she may do such as, leaving, taking any money she could either from me or the children, running up the credit cards, wanting a divorce, making up incedible untrue stries. I didn't listen. I've been with this woman for 28yrs. being a mother and looking after our house was her life. She moved out Jan. 1, I hepled her and gave her all the cash I had. She said, she just had to think and there was too many memories in the house, it just confused her. Mental health explained that his was true and that I should just support her. Two weeks latert she went to Florida (was afraid to travel) came back a week later and announced she wanted a divorce and the money fron the house. Since then she has stood up in court and accused me of being abusive, controling, stalking her, threatening her and anything else that can gain her more sympathy. Right now I am under dourt order to sell my house, and pay her 940/mn. support. The advice I need is how do I face my children? Their mother has left, and won't have anything to do with them. All she does is go out drinking, she took the RRSP money that was suppose to pay for my daughter's wedding. she called the police on one son, and told my other son where to go. I was recently told by a womon that has known us fpor 23 yrs that is my fault, that I shoud have seen it coming and protected my children, sine I am the father and it is my job to protect them.
