May I humbly suggest a strategy which worked for an aunt of mine?
She was a Witness who was married to an outsider who was very definately opposed to the Witnesses. For many years their life was filled with arguments about religion and he just stiffened up and got harder. Then one day she decided all the arguing just wasn't worth it and stopped trying to convert him. Within a few years my Uncle's attitude changed dramatically until he decided to ask the elders in my aunt's congregation and was very much pro-Witness when he died. The very same strategy can work in reverse, though it will take a long time and much patience.
So what I am suggesting that you don't argue religion with her and do not agressively try to show her what is wrong with the witnesses. In this phase of her experience with them you will just push her farther away. If you are religious, pray for her. If she does have a restraining order out on you, stay away. When you are around her, be nice and avoid the topic. If she does push the point, just remind her that she's already told you that she isn't interested in hearing what you've found out and unless she has changed her mind on the matter you would rather not discuss it. Otherwise, always treat her, and her new found faith respectfully, and insist she return the favor in regards to you and yours. That way you control the situation rather than she. And you set the tone for your relationship.
