Just wanted to say I feel your pain your my friend. I caught my W on a dating site and found an account exchanging pictures, planning weekend getaways after she tricked me out of the house I built for her and my stepkids under the guise of us "taking some time".
I know it feels hopeless at times, but given she is openly saying she doesn't know what she wants I think that bodes well in your favor. By my own admission I flail with the DB principles. I see 25 and Starsky and Cadet here are providing you advice, they are very wise so listen to them and apply. Listening is easy make sure not to botch the application like I have. My advice to you is to read DR and absorb the 37 rules and apply them.
I know you probably feel you are the only one going through this, I used to feel that way. Trust me in that you're not and it does get better in time.
Keep your chin up and make yourself a man only a fool would leave!
