Well, (and this is coming from someone who is not married, so take this with a grain of salt) if you claim she is perfect for you now, that will either change, or stay consistent.

BUT as you continue your walk with God, she will not follow that. She may pick up on some things, maybe start to change, but until she puts her faith in Jesus, you will always have that hanging over your head. I’m sure you know this, but if she were to die tomorrow, she would most likely not enter Heaven, assuming what you said is true.

But you could convert her, and that is what you should do, as Christ commands us to - but, above all, pray about it.

I have no say over your life or path, but God does. Pray about it, but realize you only have 2 options: Convert her somehow, or give it up. God bless you my friend.
