Welcome! Some people engage in what's called intellectualization. It's a defense mechanism where they can talk about even what would normally be very painful experiences as if they were just describing it as an outsider, with none of the usual emotions.

I suggest you talk to a mental-health professional about it. I really was that way for a good while. For example, I went for a whole year in therapy, talking about how I was emotionally abused and I never shed a tear. But now I am more in touch with my emotions--and even was able to feel the hurt and anger as a result.
