I've gotta say that once I accepted that divorce was ok, the idea of getting divorced became more and more attractive. It took me awhile to go through with it, but I'm glad I filed when I did.
Mine is dragggging out, although we go to mediation on Tuesday. (I filed March 1st, so it takes awhile.) Let those emotions out, and just go with it. But yes, realizing that it's a legal constraint has made me a bit more cynical, and at the same time, relieved about the whole thing. It also really made me think about what really is sacred in my life - I figured marriage was, if anything. Well, not so much. The reprioritization helped me heal a lot too.
Good luck,
