Question for Melissa Orlov

I've been reading a lot of the posts on this forum as well as your blogs and it's helped me to understand so much about ADHD.  One thing I am still struggling to understand is the lack of attention to loved ones.  In one of your blogs you said ADHD is a dysregulation of the attention system, that a person with ADHD focuses in a dysregulated way and it's hard for them to focus on something that's not interesting.  This is what really helped me to understand ADHD more.  But does the lack of attention to loved ones mean they are not interesting to you?  How can you lose interest in someone you love?  I feel that if you lose interest in someone, you really don't love them.  I would appreciate your thoughts on this, and from anyone else who would care to comment.
