I have intense sex with the neighbor's wife, she is a mature Christian and doesn't want to go to church anymore

She is a Christian mother that I met in another church in another city, little by little I was falling in love with her to be able to have sex with her, I told her that I was waiting for marriage to be able to have sex and she did not hold back and we started to almost every day, now she misses church to come to my bed.
