I could tell you, but to be honest my situation is not your situation, what I did and what happened will more than likely not be what you do or what happens to you.
Yup. I don't see things happen as quickly as they did with Sweetheart--at least the legal part. some file quickly and it's over, some file and then stall--that's common, and others don't file--ever or for years. In those cases the spouse may end up filing. Some threaten, some never mention the word.
Most eventually stall, but not all. Don't read into it.
I contribute a large part of where I am to Luck. I stood my ground, but so have many others, and their results have not mirrored mine.
You are right, you can beat this thing--though beat is a tad violent!
You can come out of this with your marraige intact and can rebuild it to better than was possible before.
But before you are even close to that, you need to get out of panic mode. Stop and breathe. What can you do that is for you alone?
