Dreaming of Boyfriends Past

I keep dreaming about the same old boyfriend. The one that went to the Naval Academy. I wonder if he still thinks about me. I also wonder why I keep dreaming about him. Part of me wants to contact him, but he is married with two children and that would just be really awkward. His wife was my replacement. Well actually, he cheated on me with the woman who then became his wife. Now granted this was from our college years (so I’m not still holding a grudge), I can’t understand why he he appears so often in my dreams.
