He seems to be a perfect match, let him convert first and find and explore some intricacies of this religion. One year is enough for him to find out if he wants to stick to this religion , or he is just window shopping and for you too, to judge his seriousness to this relationship.
You can make up your mind in the mean time too. I am sure once he makes a commitment to religion he can keep his commitment to you too.
I will pray for success of this relationship.
