Does your wife have a trauma therapist she works with?
I'm a Survivor and a wife. I personally want to know what my husband wants out of our marriage and how he feels, however, timing is everything. How it is said is everything and of course WHAT is said is everything.
Could it be how you are attempting to convey your feelings could use some outside input from a third party that is working with her? The old "I" statements can be effective until they come out sounding like accusations:
I want the old you back. I want you to go back to work. I want to know when you will be better.
(I'm not saying you are saying these things but you get my drift.)
Since it's difficult to know which feelings you are trying to let her know, it's hard to help you out here. My husband works very hard and yet still I get triggered over a look. It just happens. He has gone in and spoken with my tdoc. I would hope he does again. This is just one suggestion.
As Anna pointed out your wife is just 7mos sober and that is a short period of time. I agree that writing them out is helpful, I would also reread them several times before thinking about giving it to her.
It's obvious you care very much. I would always start off with that. :)
Peace,
