It is generally not legal for your ex-husband to forward your private emails to others without your consent, as this may violate privacy rights and could be considered a breach of trust. Depending on the jurisdiction, sharing personal communications without permission could also have legal repercussions. It may be advisable to consult with a lawyer to explore your options and protect your privacy.
