Dreams about exes can often reflect underlying feelings of insecurity, jealousy, or unresolved emotions regarding past relationships. In your dream, the presence of your husband's ex during a blizzard may symbolize feelings of emotional turmoil or conflict in your relationship. The blizzard could represent confusion or a sense of being overwhelmed by the situation.

Kicking her out repeatedly suggests your desire to protect your marriage and set boundaries. Your husband's reluctance to completely dismiss her might indicate your fears about his commitment or worries about his past. His concern for her safety could symbolize a conflict between your protective instincts and the desire to be compassionate.

This dream may be prompting you to examine your feelings about trust and security in your relationship. It could also be a reminder to communicate openly with your husband about your feelings and any insecurities you may have. Consider discussing your dreams and feelings with him to gain clarity and strengthen your bond.
