Tell her you'd like to study if she can answer a few things that are troubling you. Tell her that the reason you've not engage much with her is that these things are tough to understand.
1. JW's taught for years that the United Nations was the scarlet colored wild beast mentioned in Revelation. Yet for 10 years they were a member of said organization. Only when a news story was uncovered did they retract from their membership.
2. JW's teach that they are the only true religion and God's only channel, yet Governing Body member Geoffrey Jackson at the Australian Royal Commission investigating Jehovah's Witnesses and their 1000 plus child rape cases never reported, said that witnesses were not God's only channel.
3. JW's teach that the eating of blood is improper, I would agree in speaking of eating animals they should absolutely be bled properly however when incorporating life saving blood transfusions in this ban seems to put this law above the sanctity of life. Additionally in Leviticus 17:15,16 the penalty for eating blood was to essentially bathe and be unclean until the end of the day yet if a witness willfully takes blood to save their lives they're disfellowshipped. How is this consistent with the punishment laid out by God?
4. JW's have taught that they were chosen in 1919 by Jesus as stewards for his people. Yet most of the teachings at the time of choosing have been abandoned and worse yet been proven blatantly false. For example in the Finished Mystery it was taught that the last days started in 1799 NOT 1914, That the Alpha and the Omega was Jesus. that the one riding the white horse was the Pope, that the Leviathan was the locomotive and many many other things that have been completely abandoned. Not to mention would be likely considered apostasy today. Just because it is old doesn't mean it is invalid for if it is than the 2600 old bible should be considered invalid as well.
5. JW's teach that only they will survive. God will essentially kill 7 billion plus and only save Jehovah's Witnesses. This despite the fact that there are thousands of religions, 100's of bible translations and it is the luck of the draw if a person chooses the correct one. If God gives us freewill then the person must choose among millions of combinations hoping they get it right or they are destined to die.
In the above questions they are impossible to answer. Many of these were posed to me by a study I had no way of answering them which caused me to come to my senses. However there is no guarantee as some are actually attracted to the idea of the truth rather than the actual truth.
All the best...
