(((hugs))) I''m so sorry. Reading your story reminds me of my first few weeks when it seemed like Every Fricking Day something else would come to the surface to kick my guts out again. As many people here have said, it''s quite often not the actual affair that kills a marriage, but the TT (trickle truth) of lies that are exposed over the course of time.
Right now, you need to take care of yourself. Make sure that you''re eating, get some sleep, and stay hydrated. Please look up in the upper left corner, in the yellow box, and click on The Healing Library. Start reading. There''s a lot of good information in there for you written by people who have walked the path you''re walking now.
Come back often for support. We''re all here for you.
