At times, I can be very analytical and fact-minded, viewing the world in an objective way that would creep most people out or make me seem like an arrogant, intelligent dickwaffle. The only people I display this to are one or two of my absolute closest friends, because sometimes when this personality trait manifests strongly it is perceived that I'm being an asshole when I don't mean to be, and these friends relate. My girlfriend of three years is not one of the people I show this side of me to, for that exact reason. I can't help it when it happens. She doesn't often give me straight answers for some things, particularly when I ask about certain behaviors of hers (flicking my forehead after a very mild annoyance, refusing to show or accept affection for short periods of time after very minor disagreements, etc., supplying inquiries as to why with only "Because I said so," or even worse "Because."), and this annoys me immensely. She is aware of this. I never bring it up because I don't want to seem like an asshole and cause her to react as previously stated. Likewise, I've noticed she displays affection at levels inversely proportional to the likelihood of us being seen doing so, compounded by how high the individual who could potentially observe it is ranked in her personal respect hierarchy, and proximity to the person(s) (many long, passionate kisses when alone together v.s. sparingly few smooches when in close proximity to people, esp. family, and only when I insist, even if the people are in other rooms, unable to see us, and unlikely to approach). This is starting to make me feel like she's almost embarrassed for people to see us being affectionate. It doesn't help that I already have anxiety problems and generally don't like myself, and even after three years together still do not fully understand what she sees in me (I simply accept it as it makes me happy and it seems to make her happy). Furthermore, I do not have very good people skills (again, anxiety and self-doubt bordering an inferiority complex). How do I address these issues with her without seeming like an asshole, like a robotic weirdo, or like I've been hiding a part of myself from her?
