PM, I don't know what to say. I know that there are those on this forum who would say this is cake eating, you need to set boundaries, stop having sex with her, etc. But I honestly think that each person needs to follow his or her gut sometimes. WASs do likely have a lot in common, but they are not all wired exactly the same. Our connections with our spouses are not all the same, and not all spouses will react the same way to the things we do.
It seems to me that your W still loves you. That you still love her. And beyond that, who knows. Your W probably doesn't know. To me, "cake eating" is something that is more intentional. For example, H leaves W because he decides he wants to live the single life, no regrets, thinks it's great, intends to D his W. But knows that W is still pining away over him and wants some action, so booty calls her. Or, another example - W is having an A but isn't entirely sure it's going to work out, so she keeps stringing along her H to make sure that she can choose which one she wants if she has to. I guess you can define cake eating however you want, but to me, there is a bad/selfish intention on the part of the cake eater. And for some reason, I choose to believe that your W has no bad intentions in this regard.
I don't know. Maybe it's because my sitch isn't *that* different from yours, or because I think PM is a great guy and I am rooting for him, but I just want to say, keep it up. Don't view her coming towards you as a time to back off or set boundaries. Let it happen and see where it goes.
Just my $.02.
