Not saying that there's anything wrong with it, just that you do it for you.
Let me ask you this: If you're ready to date, why do you care if your W finds out one way or the other? If you're dating because YOU want to date, it should be irrelevant to you whether or not your W finds out tomorrow, a week from today or 5 months from today.
Also, regarding dating, are you two officially separated? Might want to contact a lawyer/do a little research. If you start dating and the sitch moves toward D, you want to make sure your W can't take you to the cleaners.
