It is not permissible to talk to your fiancé except in a case where both parties trust one another and where the parents agree to the marriage and have no objections.

The one who is a carrier of hepatitis B or has the disease may get married to a healthy woman or a woman who is infected with this disease, if she accepts that after he tells her about his situation. It is not permissible for him to get married unless he tells her about his sickness, because concealing that is deceit which is prohibited. If he conceals it, then his wife finds out about that, she has the right to annul the marriage.
