The Saga continues...

So the lying has let up some, but it continues.  Words said to my face are frequently proven to be not true by my snooping.  I don't want to live like this.  I was told that our relationship was over.  I agonized over that reality and finally came to terms with it only to find out that now she doesn't want that!  Now, I am torn over what to do.  Do I stay in a relationship because it's the right thing to do or do I continue to move forward with the finality and kiss 16 years goodbye?  This blog was not supposed to be this way!  My life has become a confusing mess.  If the marriage dies now...guess who the bad guy is?  I feel like I am in a no-win situation!
