I'm relatively new to this too. Good idea not to make any decisions while your emotions have control. I know, when do they not in this situation we have all been drug to?
The important thing, and something I still struggle with, is to focus on YOU and the kids. You have no control over your W, and the truth is, none of us have ever had that control.
The process is not going to be easy. But nothing worthwhile is.
Deep breath and relax. If you are religious, pray, and pray often. Many times, that is all that gets me through the day.
And, stay in touch with these forums. There are many otehrs her that are going through the same situation as you, as well as others who have WAY more experience than me who will help.
