C, hang tough. No one said it would be easy, but it will be worth it.
Just curious, are you really that opposed to having a heart-to-heart with your W about these things you express here? Did you cover any of that in MC? I'm just afraid that she's doing just as much second-guessing as you are, but neither of you are really getting deep with the other. I know there have been opposing mis-queues in the past, it just seems like it would be good to head off any current ones sooner than later. If you broach the topic and she tells you she absolutely is going to get on with life without you, at least then you'll know. Anything better will just be icing on the cake, and still you'll at least get to know.
