Kissing Hello

I don't know much about Columbia's life. He won't tell me much. I don't tell him that much either, but my talkative and narcissistic nature has leaked out plenty. He'd tell me if I asked, I'm sure, but I recently received some advice: don't ask a question if you aren't sure you want to hear the answer. For now I'm not sure. I know there's some girl in his past who never fully went away. (once again social networking ruins my ignorant bliss.) I'm not secure enough with our relationship to ask about it though.

I'm not sure I need to know either. There are other things bothering me. More pressing insecurities. He doesn't kiss me hello. He doesn't touch me in public. He might hold hands but only maybe. I have to ask for affection, and have to press hard for enough sex to meet my needs. His kisses are staccato, caring but rarely hungry. He is stressfully awkward in the same social situations I need to thrive. He can't make a decision about anything and criticizes my decisions unabashedly. If I ask him what or why or how about anything the answer is inevitably "It's unclear." It's as if he puts no thought into the world around him. A total lack of social awareness.

Am I just having trouble understanding someone who's a little different than me, or is this a fundamental compatibility issue? Am I asking too much or just not getting what I need?
