Hi H. -
This has got to be hard for you, and I'm sorry for the trial, but in it, you are only responsible for what YOU do, how YOU respond. You mentioned faith which is promising that you know and love God. While you are totally unable to change your husband in any way, nothing is too difficult for God! Yea! and Praise the Lord! In that, you have hope!!
It happened so many times in my own life that my husband would be 100% wrong! A favorite thing I would say is that if you asked 100 people, EVERY ONE of them would say HE was wrong! And that was probably true, BUT!! In EVERY instance, God was using the tribulation to change "me" more into the image of Christ Jesus.
I remember fussing with Him, "But, God, that's not fair!" He doesn't judge 'fair' by our self-centered standards though, and I will tell you this - - once I surrendered to Him - my Heavenly Father, and was obedient to Him (which is ALL I am responsible for) it was like I could see Him changing my husband DAILY! It was truly remarkable to watch how Holy Spirit moved and worked in my husband to bring him around to doing what "he" was supposed to do according to God's Word!
: )
Now to know what YOU are respoonsible for is easy to find out. Go to the Word, get out your Bible and look up all the "wife" scriptures - - and if you come across any "how to treat your brothers, better read them, too, because he is also your brother in Christ (hopefully you have unequally yoked yourself).
Remember the purpose for your creation - to be his helpmate. Remember your vows - better or worse. In James, you'll read that you should count it all joy when you go through trials and temptations, so be glad in the midst of this hard time - you can be glad that God is on your side. You can be glad that he's at home and not out at some bar getting drunk and hitting on strange women! Ask God for some of His joy when it gets particularly hard, because the joy of the Lord is your strength!
Be kind and use soft words. Don't try to be his Holy Spirit. No nagging. YOU stay "right" before God then stand in your faith and watch Him move in your behalf!
Also, H. - ask those people you trust to pray for you and for your husband - you don't need to talk about all his shortcomings at length - just ask them to pray. I'll poray now : )
Father God, I lift H. and her husband and family to You and ask that You would reveal Yourself mighty in their home that You would be glorified! Help H. to be patient and kind in every response and speak to her husband as to his responsibilitites toward his family. Father, You are able and NOTHING is too difficult for You. I thank You for moving on their behalf and pray all in Jesus' name. Be glorified, Father! Amen.
