Is it normal to act like this...?

Is it normal to think and act a deliberate way in order to elicit a desired response from people? For instance, this is an example of how my brain works;

In high school, my female friends would come up to me complaining about boys or other things, and I felt completely disconnected and disinterested in what they were saying, however, I fake emotion really well and I act interested just because I'm always trying to gather information, I can never know enough about any topic. I search through my head to think of appropriate response to statements they make, responses that I've witnessed in similar social situations that I sort of adopt. I am always the person people come to for advice or just to vent because I listen. I act like this around pretty much everyone I know except for a few people who I actually connect to. I'm not a psychopath, I have emotion, but I usually only feel anger or anxiety most of the time, but I'm excellent at hiding my feelings.
There are many times when people have said things to me to make me respond violently or angrily, and in my head I imagine just snapping and strangling them or head butting them, but on the surface I always keep my tone calm and I try to be articulate and not insulting. Every once in awhile I lose it but it's usually when I'm on my own thinking about things and it overwhelms me.

I'm supposedly on the Autism spectrum for Asperger's but I'm not sure if this is related to that or not. Does anyone else experience these kind of things?
