Whew! That is a lot in a month in a half. Cadet gave you some very good advice. All of it is very hard to do. How do you breathe, eat, sleep, and exercise when your whole world feels like it has imploded?
Time will force you to do the daily stuff. That will pull you through part of it. Get a good supportive friend- not your family who will tend to ally and possibly not forgive or at least not forget when/if she comes back. You need a friend who believes marriage is worth the work you are willing to do and will support you. Re-read the sections of the book that seem applicable to you. Keep posting and perusing the boards for others who have walked this road.
And as Cadet wrote, believe NONE of what she says and only half of what she does. When the WAS (Walk Away Spouse) moves out their memory plays defense, erasing all the good from history so they do not feel confused or guilty. Give it time and give it space so that the good memories and the value of your shared history can be seen. Also, moving out gets tough after awhile (lonely, expensive, not as fun..)and this will work to your benefit. However, the more you push her or hold this over her, you will cloud her vision of the relationship and she won't see the good, just you pushing her. Detach. Let it all work in your favor.
While she is off having "fun", take the time to re-introduce some real fun into your life. Marriage can easily drag us into a rut where we let our passions and interests fall by the wayside. Be sure the interests you now pursue truly revive and rejeuvenate you. Sometimes it is hard when you are so sad, but you will find after you take the first step toward happiness the next and the next come easier.
As Cadet said, grab this gift of time and take care you. Your best efforts at reviving your marriage are in reviving your best, happiest self.
