2TH, I think you have already pointed yourself in the right direction with the idea of detaching.
I feel like you talk about a lot of the hurtful things your W has done/said, but you seem to still have her on a pedestal. Do you agree? I have found that looking more honestly at my M and my H (both during the M and now) has helped me to strip away some of the desperation I felt to have him back . . . that's not to say I don't want him back - I do. But it has helped me to focus more on myself rather than my H; and to be able to look at H and his behavior more objectively and see that it is a reflection of him and not of me.
As far as dating, do you really want to date right now? Or is it just part of a strategy to get your W back?
