Pretty sure this is a MLC or Identity Crisis

Wow. Know I know where my D get her temper tantrums from! W notified me via text she was going out tonight. I said please be safe and have fun, even asked if she wanted supper before she left. She replied no. When she came home she stormed in, slammed the door to out bedroom and procedded to get ready. Meanwhile I had been doing housework the whole time, kinda ignoring the tantrum. She then comes out all hooched up with her F me boots on and tries to make sure i know she is going out. Told her have a great night. I was almost having a hrad time trying not to laugh at the sitch.
-Mach, I have been reading the resources every night and at work. Work is slow and it actually helps me as a therapist. I am seeing a lot of the mistakes I have made counseling couples, so if anything comes of this I will at least hone my counseling skills and help others. i am also reading Jim Conway's book.

Alright, another question for ya'll. My MIL and FIL are great people to me and I want to make sure that they know that whatever happens, I will make sure they will have access to visit their granddaughter. I know that this is a #1 fear for grandparents. Problem is that they kinda are a reason why W is like this so if they know what's going on, they will probably give her hell and then crud rolls downhill. However, she may also lie to them to get money (has been past experience, just finding out now)and use it to lawyer up. I know that I can't control what they do, but i know that W will wait until the last possible minute to tell them (after D ink has dried 20 yrs. :)) I did give her an ultimatum weeks ago that she needed to tell them about separation by Aug 1. (moving date) or I would. That may have been a mistake, but do I follow through. Looking for opinions and suggestions from the experienced.

Thank you for all your help! You are very valuable to me. God Bless!
