Welcome to the board. Sorry you have reason to be here.
I know you want your wife to come back, but I think when the LBS has serious issues (such as being controlling), the spouse often wants to see evidence of change that stays over time before they are willing to commit to the marriage.
It sounds like you are on the right track with your personal changes. Is you counselor working with you on the control issue?
