I think you probably are letting out that resentment, it seems to be common trait of reconciliation. I think it's a lot like the downer after an adrenalin rush. You've been 'going through the BD' motions over the last couple months. Now that your guard is letting down and you are getting more comfortable with W, some doubt is coming into play. If you are comfortable at some point in where you guys are in reconciliation, it may be good to talk about some of your feelings with her or with MC. Don't tuck them away, as that's the worst thing to do, they just will fester.
