My opinion: It always starts with the individual, in this case you. The problem has nothing to do with your husband. You, and only you have to reconcile yourself with the Catholic Church first (hopefully, your husband will follow your lead). I suggest the “5 steps” 1. Pray (The Rosary everyday) 2. Confession weekly 3. Holy Mass (the Eucharist) daily. 4. Fast (Wednesdays and Fridays, figure out what would be best for you). 5. Bible study (ie. Jeff Cavins). Your husband should do the same. When you both can stay in the state of Grace, you and your husband will grow closer and closer and discover God’s plan for you. It will not be easy. It might take many months or years and both of you probably will be tested along the way. I will pray that you perservere.
Ask for all in the name of the Father, Son, and the Holy Spirit.
