Greetings
Nick1993 ,
Please understand I mean no disrespect at all with this reply. I am however going to be totally straight forward do to the seriousness of your situation.
Let's look at scripture
2 Corinthians 6:14
Don't team up with those who are unbelievers. How can righteousness be a partner with wickedness? How can light live with darkness?
Be ye not unequally yoked together with unbelievers: for what fellowship hath righteousness with unrighteousness? and what communion hath light with darkness?
As one can see it does not say, unless otherwise one promises to change or become a believer.
No Sir, you did this on your own.
It was your desire and will and or choice.
Now you have to deal with this.
Seeking advice from people is pretty foolish when as a born again believer, all that matters is what the Author of this scriptures says.
Man, you need to spend some serious time seeking God and following His desires. He is the only one who matters.
Seems like you are more concerned with what your family thinks then your wife's spiritual wellbeing.
I figure you must be a born again Christian since you came here.
Repent and draw close to God and find out how He wants you to handle this.
Put your wife's spiritual wellbeing far above what any family member feels.
We will be lifting all this up in prayer but the bottom line is all up to you.
Blessings
