meaning of dreams dating

Well i have been dating this guy for awhile. We have had problems. He has hurt me in many ways. I keep having this dream that he is at my house, and were hanging out laying down. Most of the time we will be in my bed just cuddling with each other. In my dream i will get up to turn on the lights or get a drink, or something like that, and when I go to sit with him again,hes gone. He is either down the street or getting picked up far away. Then i get really upset and try and chase after him or get him to come back, but he just leaves without saying goodbye.
