I didn't see you mention it, but has she said WHY she's going back to penteville???

Have you considered this is maybe a storm you need to weather together since you'd planned on spending your lives together? I'm approaching this in terms of a marital-like commitment. If, god forbid, my husband announced he was going back to charismania I'd be horrified but not jump to the conclusion the relationship was over. I'd try to (IMPATIENTLY, I admit!) wait for him to get it out of his system or at least work on a way to live together peaceably. I honestly don't mean that in the holier-than-thou way it sounds. We all have our issues we cannot tolerate so maybe this one is one of those for you. However, after 18 years of marriage with plenty of bumps along the way I can say it's worth it to commit to someone and work your butt off to make it work. It's very hard work a lot of the time, but the rewards are incredible.

Also, my guess is her re-conversion isn't going to last. Maybe it's just my perspective, but once someone has experienced freedom from pentecostalism I don't think it's possible to go back permanently to that prison. She can try, but it most likely isn't going to work out.
