Inverted Personality and Relationships

I'm still pouring over old mental records and I've located something odd concerning my behavior.  When I'm attracted to someone, it seems as though I turn into a super feely-need-to-be-hugged-show-me-affection type of person.  I don't know why I do that, but I simply do.  When the person I'm attracted to doesn't show the level of affection I want, I become disappointed and start to lose interest even though I know they are still attracted to me.  It doesn't make any sense at all.  Why does my personality do a 180 when I could potentially enter a relationship?  Turning into a super feeler will only screw things up because I simply don't know how to act.  My mind is one crazy and mysterious thing
