Hi Dana -
Your dream seems to indicate that your husband’s friend pays more attention to you - and protects you - more than you feel your husband does. He is with you during the party and holds your hand to comfort you.
On the other hand, I have to wonder if the crime that is about to be committed, in the dream, isn’t one of passion - between you and your husband’s friend? Are you the criminal? The one who has been having “illegal” thoughts about having an affair with your husband’s friend? If you are attracted to this other person you may be feeling guilty about your attraction.
The dream has stayed with you for two weeks because it is significant - it has struck a “chord” within you.
