HTTE, I know it's tough, especially when she is acting sweet. I know how that feels.
From your post, it looks to me like that at one level she is being truthful, she doesn't want to screw you over. However, it also seems like she is testing to see if she still has a hook in you.
I'm not sure where things go for you. It seems like life is pretty good for your wife right now and that makes it easy for her to be sweet. I suspect that if you take a stand or draw a boundary that causes her life to not be so good, then she will stop being so sweet. In either case, she is shifting her responsibilities onto your shoulders and will probably continue until you stop letting her do that.
