Dream Interpretation: Ex dreams

Visitor's Dream: 'Called ex boyfriend from phone at wal- mart by his house but when he answered I hung up. I have not seen him in 10 years or talked with him but we had a very intense relationship. I am married and have been for 8 years. In my dream I remember that when he (the ex) answered the phone all I could think about was I can not let him know who this is and I can not do this to my husband. My ex an I had a very unhealthy jealous self destructive relationship on both sides, we brought out the worst in each other but we knew each other better than anyone else.'
