OK, I misread your sentiment. Which is easy to do online. I'm the same way -- my IC asked if I was angry and I just did not feel angry. Frustrated at the situation, but not really angry at the person.
I thought your statement that she would be required to "fill in the gaps from the past 5 months" sounded a little ... angry. Not sure what you mean by fill in the gaps, but if your W does want to work on the marriage, it may not be exactly on your terms, exactly the way you want it, exactly on your time line. Sandi2 talks about how long it takes to feel remorse, and it can be long after the W chooses to return to the marriage.
