AFWAW, Good job on controling your emotions...perhaps it would be best for you to work on your pool while she is there or clean your jet-ski. No need for you to just sit and listen to her...if she wants to talk let her come to where you are, either your garage or the pool, otherwise she can talk to your daughter. If you had someone helping you would be best. Keep the conversation about your daughter. Use this time to build your resolve up...you are probably going to have to expose and/or file to fix this otherwise you will wonder for the rest of your life...trust is very hard to rebuild after it is taken away.
Stay calm, hope for the best on E-8, how unusual that she wants to stop by tonight...I wish you had told her you were taking your daughter out to eat to throw her off.
You are doing well...yes you were down for a bit but the measure of a man is you keep getting up and take care of your responsibilities and prepare your daughter for her life.
V/r,
PS
PDT, Thanks for your kind words...you will never know how much your advice has helped!
