1) Drop Mr. Nice Guy and stand up for yourself (read. No More Mr. Nice Guy, you seem to have a touch of Nice Guy Syndrome with the admitted passive-aggressiveness) 2) Talk to a L. She already has. D is a legal process so you have to be prepared legally 3) Shift from trying to save your marriage to trying to save yourself. This is a big one. Trying to save the marriage results in actions that work against you. So work on you: 180 (launch into a new era of self-improvement) and GAL (when you get home stay busy. Every minute you aren't with the kids or sleeping, you are busy doing other things!) 4) Detach emotionally from this woman. What she does and says should have ZERO emotional impact on you. This one is very very tough. GAL helps immensely with this. But trust me on this, she wants you to react. She needs you to react. She expects you to react. When you remain calm, cool, pleased, happy, content, no matter what she says or does the impact on her will be profound.
5. When you do #2 and everything else that you do is to FIGHT for your children. Make sure that you get visitation or 50/50 custody. Do not settle for anything less.
The most important thing for you to DO in this process is be the BEST DAD that you can be, and that includes being involved with your children.
