<human>: I need some help in shedding some light on some of my views after a nasty breakup. She was not happy with my attitude in the relationship, and she was right. It's painful for me to think back and analyze my behavior, and to realize how big of a dumbfuck I was, when she was throwing love at me, and I couldn't do the same. She's the best thing that ever happened to me, and a person so wonderful I don't think anyone could not like her. Yet I somehow managed to not have that spark for her. I'm trying to understand why.

Starting with physical attraction, I can sadly confess that I never really was attracted to her fully (her face and body type wasn't very attractive to me), but neither the opposite. She has a nice body, little to complain about. I liked the way she looked, and I was seemingly satisfied with that, but somehow I always thought there are more attractive girls around me. I tried to ignore this, because I didn't want to be superficial, and in a serious relationship there are other things more important, I think. Mind you, sex was never a problem, I was turned on by her instantly, any time, anywhere. I do have a high libido, though.

Her personality was unfamiliar to me. She's a good girl type, but not the conservative type. She was really up for anything, kind of in a weird but in a good way weird attitude, fun loving girl. She's a positive, extremely trustworthy, supportive, smart girl, with lots of added extras. Yes, sometimes I was missing some things in this also, but I never expected perfect. There was nothing seriously lacking.

So what happened? Why wasn't this enough for me? Why couldn't I be so excited to see her every day as she was to see me? Why couldn't I smile so big when we met? Could a lack of bigger physical attraction make me feel this way? Would that matter later on, when we were older? I just can't shake this feeling that she was almost perfect, and it wasn't good enough for me. I'm certain I won't find this unconditional love easily again, yet I couldn't treasure it when I had it. What's wrong with me? :(

Can you condense the text into three sentences or less?
<bot>: Was physical attraction the fault? Is it that important in a relationship? Why do I see the grass greener on the other side?
