Welcome to SI and sorry you're joining us. I'm going to refer you to the JFO (Just Found Out) forum. There are some posts pinned to the top of the page that are really good resources, as well as other posts that have bull's eye icons. The Healing Library is at the top of the site and is another excellent resource.
Yes, several members have found out that their WP (wayward partner) continued the affair. There are only a few that still post that had a successful R (reconciliation).
Please see a doctor and get checked for STDs/STIs as there are some nasty diseases out there. Also, if you're having trouble with anxiety, depression or sleeping, ask your doctor for some meds to help you through.
Dating is to check to see if you're compatible for M (marriage), and she's failed the girlfriend test. Do you really want to bank on her changing? R is hard work and both have to be in it 100%.
She needs IC (individual counseling) to work on becoming a safe partner. If you can, IC with a betrayal trauma specialist to help you work through the trauma.
She should read How To Help Your Spouse Heal After Your Affair by Linda MacDonald. Although written for married people, it's easy to adjust for non-married situations. It's a nice blueprint for a WP. Another good book is Not Just Friends by Dr. Shirley Glass. It's more fact-filled and has some great advice.
She needs to find a new job, pronto. She needs to provide you with a written timeline. Not just dates, but should include feelings, thought process, etc. Electronic transparency. And NC (no contact) with the AP (affair partner).
In the JFO forum, there are some posts regarding consequences. One thing to think about is what happens if she breaks one of your boundaries. What will happen then?
Sorry you're here and please keep posting.
