Divorce Support Forums: Ex Switching Attorney

Hi,
I'm new to the forum, but have been lurking for awhile and thought I'd post for some support and advice. I separated from my wife in Nov. of 2007. She is an alcoholic and over the last few years I have come to realize that she was not only neglectful of our relationship, but was ruining all the relationships in our lives. We have two children, whom she has stayed home with since they were born. I believed they were unaffected by her alcoholism - but have since learned differently. I was awarded temporary sole custody 60 days ago. My soon-to-be ex lives in the house we lived in as a married couple and has very limited supervised visitation with our boys. She has continually gone against the court order in terms of visitation, financial constraints, calling and harrassing the school staff, harrassing other family members, doing anything she possibly can to gain control over a situation which she has clearly lost control over.
I found out Monday that she had fired her attorney and hired a new one. Her new attorney is a well known attorney in the Wayne Country area - who handles high profile cases. He costs upwards of $10K just for a retainer. She immediately withdrew thousands of dollars from our home equity line of credit - which is supposed to be frozen - per the courts orders - but she ignored.
I am a normal guy. I have lived a normal life. I was married for 14 years to a woman who I thought I loved and who I thought was caring for our 2 wonderful boys. For the last 4 years I have been living in hell with her as she became a raging alcoholic. I feel I have done the right thing by getting myself out of a situation that gives both me and boys a chance at a better life. My ex went into rehab after I left - but only stayed 12 days.
I have an attorney whom I believe is really good. She got me the temporary custody order for my boys. She has been able to keep my ex away from me for the most part.
But now with this new attorney - she withdraws all this money from our home equity line and I learned today that she is planning on filing a motion to bar me from ever entering our home again. I have never been abusive - verbally or physically. How can things turn so ugly over nothing? Has anyone else had significant experience with an ex-spouse who was very emotionally disturbed or who was an alcoholic? If so, what happened and how did things turn out?
Thanks in advance.
