Brother in law touching sister in law

Q: My brother in law tries to touch me here and there. First I didnt notice it but one day he touched my parts unknowingly and telling me that I am reacting wrong. My husband is abroad and mother in law is handicapped. My husband is telling me to leave it to Allah and to speak to him normal as if nothing happened. I feel so bad and guilty from heart because this is about my izzat. My husband says that it was all my fault.
