I feel your pain.  Same thing happened to me a few years ago.  Its good that you are taking on some of the responsibility because it definately takes two to tango.  I read on the internet that its prety common for BPD and Alcoholism to run together, makes for a nasty irritable mania.  (if she is manic an only on anti depresents...even worse)You probably have about six weeks without her to think about where your life is headed.  I didn't realize how potentialy bad the charges can rack up on you till I was sitting next to a guy with 5 DV's.  The cops finaly started to arrest both him and his wife at the same time.  Can you imagine the financial cost as well as having a record?  You will also soon become very familiar with the gender biased court system.  What I mean is.....they don't care if she is bi polar, punched you 15 times and caught your house on fire.  Just a heads up here......this problem doesn't hope itself away and the succes rate is low.  You will be fighting alcoholism and mood problems, financial jeopardy, marital infidelity and be emotionaly exhausted.  Your children will likely need counseling as well.  Enjoy the break, get lots of rest, get your finances together, seek legal counsel and whatever you do..........DONT BREAK THE PROTECTION ORDER!  Also......tell your story to the next guy that asks this question.
