It is normal to have emotions toward this, especially if it offended you. It is your right to not be around this woman if she makes you uncomfortable. However, we cannot control the actions of others (you wife). She may begin to resent you and it may cause issues in your relationship if you continue to tell her not to be around this woman. This is only my opinion and others may differ. I think that you and your wife should have a discussion and try to resolve this before it causes a rif in your relationship.
