Ever since I was little, I loved the idea of loving someone and spending my whole life with them. I treated everyone nice. For girls I liked, I would spend every second with them. It always ends the same way: I like you as a friend, or I love your attention but not you.
Attention is often something that is both wanted and sometimes not wanted all the time. Maybe when you're in a relationship with someone you can discuss the amount of attention that you are both comfortable with and/or what you are both looking for as far as amount of connection.
