First, let me apologize for giving you the wrong instructions on how to start a new thread. Good thing Lance was there to straighten it out.
Next, let me welcome you to the MLC board! It's the best place no one wants to find themselves.
There are a lot of very knowledgeable people here that will try and answer your questions.
Do not leave your home or the master bedroom. If your wife does that's her choice.
Although no one can tell you exactly how long this is going to take a rough estimate is anywhere from 2 to 5 years. It's a long journey but the most important thing you have to remember is that you are not to blame for your W's MLC. You did not break her and you cannot fix her. You can however take a look in the mirror and work on those things that you don't like about yourself. Do it for you, not with the intention of getting your W back.
Strap in and hang on tight. There's lots more to learn about this rollercoaster ride!
Keep asking questions, and if you could give us some background details such as how long you've been married, how many children, yours and W's ages, bomb drop date, it will help us be able to help you more effectively.
