New Life Wanted

Looking to start over and have a new life.  Needing funds for a divorce with children.  Married for 23 years.  Sacrificed my career so my wife could have her's and current job does not afford legal fees for divorce.  She has told me to leave but I have no where to go or any means to start separation proceedings.  Feel trapped and need help.  Injured before we were married and was a stay at home dad and raised my children while she worked and got promoted.  Worked part-time around her schedule for 20 years.   I finally have a job with growth potential but buried in debt and bills.  Wife pays only the bills in her name and not joint bills, I pay the rest.  Please help if you can.
