My Sole Source of Support Abandoned Me....

After nearly 10 years of marriage my husband walked out on me and moved in with his mother and a buddy of his.  He then moved into his GF's place, and the friend and mother are covering his whereabouts.  Now the apt. that they first moved into is vacant and my husband has gone into hiding to avoid agreed upon support payments to me.  I am desperate - I have a health condition, no ins. no money, no food, and no way of finding my husband to make him own up to his responsibilities.  I am trying to get the paperwork filed for an emergency order under a cause of spousal abuse and neglect - but stil have no idea how to find out where he is so he can be served with the papers.  He took everything I had - and then some, and when there was nothing left he walked out.  I am 51 years old and he is 10 years my junior.  He is on disability from a work related injury and has no intention of going back into the workforce.  While I have nothing, I've learned that he regularly plays golf and has been seen frequenting the local bars and enjoying a social life at my expense.  I just want what we agreed upon, which was not outlandish or extreme in the least - but it did allow me to pay my utility bills and put food in the house, which is much more than what I have now.  This man is a manipulator and has a history of indebtedness and abandonment....and he's really done a number on me this time.  I'm making myself sick with worry....and can't afford the stress of now knowing how I'm going to survive.  My health is greatly affected by this, but he let the insurance payment lapse and I'm without medical care now also.  The bad guys can't always win.....isn't there something I can do to track him down and hold him accountable for what we agreed upon?  Don't marriage vows mean anything anymore?  I am absolutely devestated by his disappearance and the loss of financial support...and my health precludes me from working, so I'm totally dependent on him.  Any help or advice would be greatly appreciated.  Thank you!
