(Disclaimer: This is what my Rabbi told me for my particular situation. It does not necessarily apply to others even in similar situations.)
When my husband and I got married, neither of us was observant. Since I was the one who grew in Judaism and he wasn’t, I changed but should not expect him to change, as long as he is not making me commit sins (which he is not, just he himself doesn’t want to participate).
Even though he remains non-observant, I should not look down on him. His frame of reference is not a Torah frame of reference, so he doesn’t know why it’s wrong to do certain things.
I can’t go to treif restaurants with him or break Shabbat for or with him, etc., but as long as he is treating me properly – which he does – then Shalom Bayit is paramount. I should focus on his good qualities and not compare him to others.
My rabbi said that I can consider all of the above to be his Halachic decisions on the way I should conduct my life and my marriage from now on.
So … it seems that now I have been given a new charge by the Al-mighty, one which focuses on mending my own attitudes. I am posting this rather intimate, personal article to ask for help in dealing with these challenges and tasks, and to ask for Chizuk, support, anything anyone can tell me to strengthen me. I am in deep pain right now and looking for comfort and healing.
