It appears that you are pretty insightful given its so early on. Like I said, your description sound so much like my WW. I didn't even realize that when there was any conflict that my WW would back down and hold resentment. I figured that we had reached a compromise, but she felt otherwise; but didn't tell me. The first I saw this come out was during BD when issues from the past came up that I never thought were big deals.
In saying all of this, you realize that you can only do what you can and WW needs to figure this out herself. It probably will get worse before it gets better as WW tries to reconcile her feelings. For me, it's been almost 9 months and WW I believe is still trying to hold onto an A that didn't work out (he never left his GF) trying to mask introspection with blaming MCS. However, I see the less and less she can blame me, the more upset she has gotten. With her friends, with me, With the kids. I think this is the same avoidance she had in our M, it's Now just between her and herself.
It's going to be a long road. Hang in there
