Alaikum salam sister.
Im sure you must be going through a very challenging and difficult state in your life but since you admit your husband is a good man shows that you are not ready to separate with him and there is a great potential in him to accept and embrace whats Good. The fact that he is not a practicing muslim could be because he is having a problem either in the ideology of Islam and its principles i.e. Aqeeda or maybe he wants to be free and not be bound to any duty or responsibility. If its likely to be the former then you can maybe refer him to a scholar whom he can be in touch with and ask all his questions.
If its the latter, then keep on talking slowly whilst having your faith intact remember that if your faith falters theres no chance of saving another persons so you have to remain steadfast against all odds.
Dont loose your faith and practice at the exepense of anyone because you will have lost the greatest asset in your life and hereafter. Latch yourself to a religious and scholarly freind who can constantly guide you and and you could be in touch with her often preferabely a community member. Keep on with your practises even if you see no difference in him and question yourself about your priorities of whom you wish to please which if you be sincere then it will only be for Allah. And that will certainly start making an impact on him. The entire Result maybe very slow but its sure to come.
I hope you can face this trial and get many rewards from it. Remember keep on praying for your spouse to get the guidance from Allah and go on with your duties towards the Almighty. After all the result of everything lies with Allah who is most concerned about all his creatures and He will surely help both of you.
