You have been advised to protect yourself financially but you are afraid to do this because you think it will just make him angry and push him to file for a Divorce.
Never do anything out of fear! He will file no matter what you do or don't do ... your job is to protect yourself and daughter, financially, and emotionally. I agree that you should let your H and daughter work on their R, while you keep the negatives about H to yourself. If your D wishes to vent to you about her dad, then just listen and validate, but don't make things worse, by adding to the negativity.
I was also confused by the A 12 years ago???
