It is really hard to be with a person who does not respect you and your spiritual beliefs. I have had a struggle with my husband over a similar problem. I am becoming a more committed christian while he is not. I tell him that he is an independent human being and he is entitled to make his own decisions about things, but if he expects me to respect him, I expect him to respect my spirituality as well. Lately he has been much more open and interested at least and we are able to have a rational discussion.

Respect if fundamental to any relationship and I find there is serious damage to communication when it is lacking. I think it is important to establish a boundary here or you will find yourself in for more trouble down the road. If he really loves you, he will respect you. If he is self-centered and arrogant he probably will not.
