I hate my dreams

I had this dream last night. He invited me over to his place (which actually in reality is MY place!) and he declared his love for me. Weird thing is he kept changing appearances and stuff. Then when i decided to give him a second chance I had to prove myself to his parents, which i do and we live happily! Point is i thought i was over him and now this dream makes me feel all happy and hopeful and i am back to freaking square one! Whatever square one is... Feeling like this i suppose. ARGH! I think i know the problem... Well, part of the problem, it's that i hardly ever think about my past relationships and friendships (All of which have obviously ended - all terribly by the way) I don't want to, in a couple of years time, forget all about him because as much as i would never say this he was special. He was an ass, sure but he was definitely special. Maybe i should forget about him. Because these feelings are driving me insane.
