Oh, Dec... I 'hear' the desperation, anger and worry in your words. ADHD can be such a complexed thing to deal with on its own without having to manage a girlfriend 'playing' like this. Does your son have any support from a counselor, therapist or someone similar, who could be of assistance to guide your son regarding this?
I know you and Kathy always do everything possible for all your children. If you would like to talk... pm me... you know my son has Asperger's and ADHD.
