What if my husband does not want me to wear tzitzit?
Because your husband is Biblically in headship over you and your family, I would first discuss your desires with your husband before you make any changes. If he is dead set on you not observing the command of tzitzit, than I would personally honor your husband’s desires first, and then bring the issue before the Lord in prayer and ask the Lord to reveal the issue and your heart’s desire to your husband. Whatever you do, please do not let your observance become a division in your marriage. The greater love walk of Torah would call for you to express love and patience toward your husband, until such time that he feels comfortable with your desire to wear tzitziyot and comes in agreement with you.
