Hi jpb4815,
Sorry you're going thru this mess. -- I'm going thru something similar; but not as sudden and abrupt as 'one day she woke up.....'

We decided to separate a few months ago; I didn't fight too hard. I'm 50 years old and just KNEW I did not want to be unhappy for the next part of my life.

Try to live YOUR life....
Maybe meet people of similar interest and similar situations; perhaps (if you haven't already) search for your local chapter of DBSA and/or NAMI; they surely have support meetings in your area.

Good luck man, and take care of YOU!
