Hey there. Welcome. I'm glad that you found us for support.
First off, good for you, for continuing to push for answers. I hope that you continued on with the scheduled lie detector. I'm sure that there is probably more that will come out in the parking lot as you are ready to walk into the tester's place.
If you have not already, please look at the upper left side of the screen for the yellow box. Click on The Healing Library. Start reading. There are some very good articlse written by people who have also stood where you are standing now. Any other post in this forum that has a bulls-eye next to it is also somethign that you should read. Information is power, and it seems that there is a lot of common bull that adulterers use when they are trying to snow their spouses.
And take care of yourself. You need to stay hydrated, eat, and try to sleep. Be kind to youself and a bit selfish. You cannot take care of your children if you don't take care of yourself. So do what YOU need to do, to stay healthy no matter how much you don't feel like it.
Come back often to vent, to cry, for support. We're all here for you.
