Dreams and nightmares

Had a dream tonight that woke me up at 1:38 am.  It was an awful dream where the man that I love was with another woman and he lied to me. I dreamed that I ran into him in a bar and he said we were back together and then I followed him outside and he was getting into a car with the girl that I had been talking to all night in my dream. I was asking the girl why she lied to me, I don't even remember what she lied about. I turned to say something to him and it freaked me out so bad that it woke me up. After waking up I realized he was really gone and never coming back. I just started crying, not just a few tears either. Full on, gut-wrenching crying. I think the reality of him not being here was so real at that moment that it was just too much. You would think that after over two years that I would have some sense of peace but I fear I have a long, long way to go. I don't understand the dream either. He was one of the most honest and loyal people I have ever known.
