They have the saying of not doing anything drastic for the first year.
I have heard a LOT of people say they wanted to divorce their spouse after getting sober. Most of them did not do it and they are so glad they waited. You really change a lot when you get sober. You are clear headed and able to ponder things you would not have dreamed of while drunk. I say hang in there, you may change your mind later and it will be too late.
As for working the steps, the best thing is to dive into step 4 (when you get back to that step- sucks you got to start over) You just have to do it- it is not as bad as people say. It gives you a road map of your life and now you have the opportunity to make things right and start over and live differently.
