Islander - I have read your posts, but have never posted on your thread before.
STBX and I have been separated for a year and a half, and will be divorced in just over a year. We still have nothing legal in place at all. I have been a "nice guy" regarding finances all the time. But this year, I started looking out for me and the kids more than before. Still, it's only money. She has taken much worse from me than that, and I allowed it.
As long as you can live comfortably when it's all over, that is all that matters. Sure, it's not what we worked so many years for, but you are only 34 years old. You have plenty of time to recover financially. The biggest recovery we can all make is in our pride, self esteem and self respect. No one can take any of that from you if you don't let them.
