This sounds like a very intensified dream that you had. This may be an expression of some surpressed feeling you may be having. Subconsciously you may feel under appreciated by your family. You do lot for your family and besides physically you deal with a lot emotionally with his ex and all. You may question yourself if your relationship is worth all the emotional stress that you handle with your husband's ex. You are a helpful person as well as a very good person, but also want to be sure you are being valued and appreciated by your husband, your family, and people in general.
How does this interpretation sound to you?
