Dopamine or just Dopey

Am I the only one that feels like some days they play more love songs than others? A friend of mine seems to think that they always do this, I just notice it more on some days than others. Either way. A and I watched the 3rd Matrix Friday night and for some reason all I could focus on was the love beteween Trinity and Neo. Seriously, is it possible? Can we really find that kind of movie screen love in real life? I know it takes work and it's not all perfect. On screen though it's so strong, so powerful. The shrinks are saying that it's only the dopamine levels and love at first sight is unrealistic. All this online crap is making me more and more pessimistic.
I got a phone call last week from a person that was part of the group I hung around with B. I haven't spoken to them since he left really, that makes it almost a year now. As I try to think of what I want in relationship, I think of what we had, and didn't have. What I hate the most is I can't tell what was real or not anymore. My love for him was unconditional, I always believed in him, and stood by him. There was never a time I wasn't thinking of him or there for him. It didn't work both ways. So was I an idiot for giving so much of myself for so little? I have his letters though, and when he did do something it was perfect. He has said though that he didn't mean it. Was that the truth or was he trying to push me away? I need the truth. I want so badly to close the door, but I have so many unanswered questions. He's not returning any of my texts, emails, or phone calls though. So it seems that I'll never know. Is it really so wrong just to want to be loved?
