I knew someone who was married to a narcissist for over 20 years. It destroyed her.
Narcissists will never ever change. Not ever!
They do not see the world or anyone in it including their own offspring much less their spouse, through healthy eyes.
Narcissism is a mental illness. It's an organic illness. It's not something someone comes into, it's something they are.
You are the role model for your children. What you do so too shall they do because you teach them what a couple is.
Some say the Bible forbids divorce. That's not true.
One thing the Bible does afford as a comfort when a person fears divorce will cause God to condemn them is this in the pearl of Jesus words:
1 John 1:9 If we confess our sins, He is faithful and just to forgive us our sins
If you accept it is a sin to divorce, consider how it is a sin to allow yourself to be unequally yoked! Some think II Corinthians 6:14 is speaking solely about those who are not Christian.
But think about it. If you're a Christian and you enter into marriage you are suppose to both honor the word as to what marriage, spouses, and that relationship mean.
He's suppose to honor his wife and children. When he's not able to do that because he's a narcissist, you are unequally yoked. You're with someone who is not able to honor the covenant of marriage.
God forgives every sincerely repented sin.
The person I knew who was married to a narcissist for over 20 years was very devout. When she went numb and couldn't remember who she was when she was happy long years before meeting that guy, she resolved to save herself and she divorced him.
She said she realized it was a sin. But it was a sin to die inside too. So she divorced and then sincerely repented for the divorce and for tolerating abuse in the name of marriage.
Today, she's single, she glows as if someone turned a lamp on behind her eyes. And she has not a thing bad to say about her ex-husband. She repented, and she forgave him for being what he is. It's Jesus who saves people and she realized she wasn't responsible for saving her ex. That's what she thought she was going to do. Thinking he'll change if she just stands behind him and prays.

May God be with you in all things.
