I think you shouldn't allow her to visit you. Most women are like that. She want to get close to you and wouldn't mind sleeping with you.Trust me, helping her family at the time of distress gave her family sense of relieve. . Did she inform her husband ? If yes, You are safe, otherwise she needs something. Don't let this break your friendship with your best friend.and if you allow her to come, you will sleep with her even if she doesn't show any interest

My advice to you is that you should discorage her from coming. Tell her your cousin is at your place doing the chores or tell her you will let her know when you need such help.
