I had that happen to me.

I met this lady and right a way we hit it off.  I knew we could be friends.  But I didn't see her again for about 18 months and then we did hit it off and became the best of friends for about 5years.  Our kids were good friends, we were good friends our husbands were friends.  They were the type of friends you went on holiday with and shared your life with.  They were having some troubles and my husband took over their accounts for a minimum fee (and I mean minimum), he looked after their employees and generally sowed hours and hours into helping them out of a mess.

The men had talked on and of about going into business together, and then just on the eve of it happening the Lord gave my husband a dream (not a Christian remember), and he decided it would be wrong for us to go into business with them (something which I had been saying for a year or so) because my husband wasn't a Christian....

Things changed, because he said no.  And that was that.  I kept saying to my husband that something wasn't right...  then one morning the Lord gave me Psalms 88:8

8 You have taken from me my closest friends
       and have made me repulsive to them.
       I am confined and cannot escape;

And that was that, a friend told me they had cut us off, well the husband asked her to cut me off.

She is now fighting cancer and I don't feel there is anything I can do, not without the husbands say so.  For it is him she needs to submit too and until the Lord moves on his heart then I feel trapped.

I/we went through a very hard grieving process and my husband yet again came off thinking negatively of Christians and the church.  He thought he had made a friend..... but came off feeling very used.

It has been a terrible terrible journey.  I am sure we are not without fault in it all either.

It has been continually heartbreaking and I am not quite sure what to do.

Wow, this is heartbreaking. I don't know the scripture offhand, but I have felt that I will have to end (or just not hang out with) some of the closest friends I have, because they are not christians. I am just a beginning Christian, and I don't even go to church yet, (i hate admitting that)  I just read from devotionals every day, and have read several christian books. I do feel, however that I need to make friends that are Christians. This is one reason I joined revelife. To learn more about the world of Jesus. 

As for you and your husband going through the grieving process, I am truly sorry, but God doesn't give us more than we can handle. ( i do, however, have questions when it comes to children) Hang in there.
