Welcome to the OPEN forum jc1985.
Sad that your "Christian" wife no longer wants to be married to you. Clearly she feels that her "spiritual endangerment" (non-Biblical phrase!) overrides 1 Corinthians 7:13, 14 - ".....if a woman has an unbelieving husband and he is agreeable to staying with her, let her not leave her husband. For the unbelieving husband is sanctified in relation to his wife..."
I hope you come out of this relatively unscathed and stronger.
