I think you need to take your time. You said that your wife is "verbally abusive", this is probably the biggest issue you may have to personally deal with, is this mainly when you bring up anything that puts JW.org in question, difficult questions for them to answer? I know witnesses who would sooner use "verbally abusive" or cry out "apostate" to protect their Watchtower beliefs.
Another thing that could happen, once your wife realizes that you are on the fade out of the WT, she may increase her JW position, doing more for JW.org to try to compensate for your inactivity.
