Expat, It's good that you have that lawyers appointment. I bet you may even feel giddy and even high just for taking your life in your own hands. I once left my husband,...just for a weekend...and after the initial tears were wept,...I thought I could leap over tall buildings. He begged me to come back. I did, and my leaving cleared many things. But mainly he realized that I mean what I say. And if he wants to keep me, changes had to be made.
Good luck in whatever path you take. Just believe in yourself!
