Troubled Friend

I have a very close friend that I have been in touch with for many, many years.  We met while I was in grade school in a small town in Kansas.  Some how, we have managed to stay in touch after all of these years.  When she was 23, she moved to Wichita and met a wealthy guy that seemed to be pretty good to her.  Shortly after they got married, 14 years ago, her husband joined the army.  As military life is, they have moved all over United States, and they lived in Germany for three years.  She actually had her third child over there.  Being away from her family and friends, she has been very lonely.  She has made  a few friends, but no one she can get too close with since they move all of the time.  Her husband is some Sargeant or something in the Army and he is also an alcoholic and abusive to her.  They have had many struggles through out their time together.  He is always spending money and not leaving much left for her to pay their debts or buy groceries.  He loves to play golf and drink lots of beer.  Even when he is away in the field, he is spending money.  He has been to Iraq twice and he has blown a lot of money while he had been there.  She has to take care of the children and everything around the house while he is gone.  It has been a lot of stress on her.  When he comes home, she has to deal with him constantly going to the golf course, drinking, and being abusive.  She has called the MP'S on him several times, and has gone to counceling, but nothing has helped.  Just before Thanksgiving, he had punched a hole in the wall beside her head and held a gun to her.  She has had to go to the doctor because she is so depressed and has been put on medication.  About a year ago, she started crying one day and could not stop.  She was having suicidal thoughts, and ended up going back to the doctor.  She ended up admitting herself to a Psychiatric hospital for a week.  She is not doing much better today.  Her husband has been hitting on her and calling her names.  When I talked to her tonight, she said that she had got the kids ready for school this morning and when she got in her vehicle to leave for work, she closed the garage door, started her vehicle, and just sat in it with the windows up for a while.  She was thinking of dying.  She is so depressed and I do not know how to help her. She don't see how she can leave him.  I have begged her for years to come stay with me, but she just stays with him.  She always thinks he will change.  I feel so helpless.  I wish I knew what I could do to help her.  At least something that I know would make her get away from him.  She is going to end up killing herself.
