Help to de-convert!

[Aoi Magi]

Breaking free from religion and staying away requires a very strong will, it's something like quitting drugs. It's next to impossible to have someone quit just through talks, rather they need some personal motivation and lots of support. As I see it, if you truly want to be with him you have to make a compromise for now and give him time. He most likely went that route because he was alone and vulnerable, so if you move away he'll only get pulled in deeper. Many atheists are in loving relationship with theists and are making it work. Don't push him away, rather have patience and hold onto him with lots of love. It'll take time, maybe years, but slowly you can make him see logic and reason again. Keep trying!
