I just needed to tell you, as someone divorced from a unbeliever, and a mother
in law,  both similar to your description.....

As someone going through raising children who get pulled by their father one
way and me the other....

You need to consider marrying someone who is not a believer more carefully.
The bible is pretty clear about not getting yoked (married) to an unbeliever.

My exhusband was raised in church, would agree in the ten commandments and
that there is a god, but also would not have taken the bible literally. We
also fought about it.....His level of belief may have made him a diest,or even
religious...

but NOT a Christian.

He sounds a lot like your Eddie, and his mother , too....It made me really
remember a lot of things...

He only went farther the other way....becoming more worldly as he grew older,
yet he thought he was secure in his "religion".

My decision to take my faith seriously was the last straw for my marriage. I
think he could not look at his reflection, of how he lives, of his disbelief,
compared to me trying to walk with the Lord.

I feel you are about to walk the same path. Your mother in law is certainly
not an ally. Neither appear to be saved, although they may be "religious".

I suggest it is not an easy path, to be in a marriage like that. If they were
truely saved, you would have the inner witness of the Holy Spirit, as you are
so close to them.

You would know, and have peace about your upcoming marriage.

It is not Gods will for you to marry an unbeliever.

Prayerfully reconsider, ask God for guidance. Follow what he says in his word.

In Christ

2cr6:14
Be ye not unequally yoked together with unbelievers: for what fellowship hath
righteousness with unrighteousness? and what communion hath light with
darkness?
