Dreaming of an ex: What does it mean?

Okay so lately I have been having dreams about an ex. In every dream I am walking outside to wherever I'm going, until I get a call. I pick up my phone to answer without looking at the caller id. When I answer it, its my ex. He calls me out the blue after he stop talking to me. In the dream I talk to him like an old friend who I haven't heard from in a while. We catch up on each other lives. But in the dream I never got mad at him for him ending our relationship by stop calling me. Anger that I thought I would have I didn't. At the end of the dream I hung up the phone feeling at ease . What does that mean?
