Being MPD - I have many inner children who are very attached to my therapist. I have one who always tells her that he misses her. She tells him she misses him too!

One way to do it is to right a letter to her, and write "miss ya!"... It doesn't come across as "serious" as saying "i miss you" and can tests the waters without making it seem like some deep rooted issue.

Just a thought - dont know if that helps.
