I don't know if it's unusual, but I tend to like to listen and get to continue to know a partner's thoughts and be there when she needs someone to talk to. I'm ISFJ for personality type, so maybe listening just comes naturally to me.
I'll typically just give my full attention to listen, take it all in, and if she wants input and asks, give input on what I've heard, and after the conversation, it all naturally just gets archived. So later when the same subject comes up, I have a tendency to reference pieces of our past conversations.
As Schneekugel mentioned, most people actually like knowing they've been given the time to be heard and their stories remembered. I don't exactly find it nearly as enjoyable, unless maybe when talking to a friend, but I typically am there to listen to anybody who needs someone to talk to, and most people seem to appreciate it and not seem to take such for granted.
Also, as AspergianMutantt mentioned, trying to solve the problem or voice your opinion sort of breaks the role of listener, and is best only to give such ideas when/if asked. My father was that way, and it was always very frustrating to the point where I learned never to come to him with my problems or I'd just get yelled at for not fixing them by one of his faulty designs. I knew how to solve my problems, I just wanted someone to talk to, and to get advice and feedback on my plans, not to be treated as inept and be handed a 10 step plan because I'm too stupid to figure out anything on my own... Similarly, I'm sure a woman I'd be dating would know how to manage her own life's troubles as she would have had to before meeting me.
