I am sorry for what you are going through. Dont blame yourself for helping her see the TTATT.
She had a choice to accept it or not, as we hear about with so many others. Sometimes the spouse decides to divorce because they still believe and the other dont and that is not how they envisioned their marriage. I can respect that more than someone who accepts TTATT, decides to leave and blames it on the other for opening their eyes. That's a lousy excuse and would've been better if she just owned up to her own true feelings about the marraige. By waking her up, you in a sense did her a favor and she is misdirecting her anger at you.
You took a big risk, but your life is not over. I'm in a similar situation and know that the more I try to wake my husband there is a risk they he may want to part ways because he doesnt want to remain with an unbeliever or he may accept the TTATT and decide we are not a good fit (we also married young). That is a risk I have to take and feel that if he feels that way, I prefer to know the truth and we both move forward to live meaningful lives. I would be devastated, but that is part of the risk and in the end I would know I did my best.
You will need to modify your exit strategy to what you feel will workout best for your own well being and your relationship with your parents. Maybe this could help you fade quicker...you could be "stumbled" by this.
Wishing you all the best.
