My husband/marriage

My husband has had a drug addiction long before we met. Since when together with the grace of God he was clean for 3 years and off parole in a year and has spent 5 years out of jail. The longest times he's been out since he was 17. He had went back to his addiction and we are now separated. I'm asking for prayer that God will break him down, and get the help he needs. Also for our children (my 2 stepchildren 8 &10 and my son 10). And for me that God can give me the strength to keep moving forward. To keep my faith. Not to give up on my marriage so easy. And to fill the empty void I feel. And give me the right words to speak when dealing with my husband and children. Thank you.
