People have given you fairly good advise here so I am going to give you some emotional advise. Do nothing permanent for one year after every thing is finalized. Two would be better.
Don't buy a house, sailboat or remarry. Settle into being YOU solo. Get to know yourself and what you want. You have spent a long time being in a team, there are things you will automatically do because that was the way she wanted them. What you actually want can be very different.
Best of luck my FRiend.
I second this advise. My first marriage lasted only 6 years and for the year after my divorce, my students (I was teaching High School math then) all suffered a one grade deficit until I got back to being myself. I looked back over the grades I gave and realized that I was not teaching very well, and must have been really tough on the kids. But you do get over it and then life seems OK again.
Thank you.
Wise advice indeed.
