I know that before I was disgnosed I had similar tendencies. It was all about me and what I wanted to do. I was obsessed with a girl (mainly the sex). We went to the gym together in the morning, worked together all day, then I went to her house for the evening until I had to have my parent's vehicle home by 11.
It got so bad that one evening my mom called me saying there was an emergency and I had to get home. When i got there in a panic and asked what was wrong, she said, "I just thought you should be home." After my first year of college with the same girl and doing the same thing that summer, my Dad and I got in an arguement about it which ended in him calling me an arrogant a'hole.
