Have you discussed this problem with your husband? If not, do! If you have & he hasn't chastised the kid for disrespecting you, then THAT'S where your REAL trouble lies!! 'cause, no matter what health problems the kid has, your husband should NOT let him get away with disrespecting YOU!!If he does, then you have BIGGER problems than a 15 year old SPOILED KID!!, 'cause,Personally, I don't believe all this "ADHD" MUMBO, JUMBO! I think, in most cases, it's just a child's way of getting attention!! 'Cause, if your husband lets him get away with disrespecting you, ESPECIALLY HITTING or KICKING YOU, then the kid will pick up on this, "QUICK" and will only get worse. So, if you've talked to your husband about it & he hasn't done anything, YET, talk again. If he STILL DOES NOTHING then,IF IT WAS ME, I'd LEAVE!! Or at least give the good-ole "ULTIMATUM" that "EITHER HE TEACHES HIS KID TO RESPECT ME OR ME & HIS OTHER CHILD WAS OUT'A HERE!!" IF HE is trying TO SHOW HIS SON THAT HE SHOULD RESPECT YOU, & IT STILL ISN'T GETTING THROUGH, THEN HAVE YOU SPOKEN WITH THE KID'S THERAPIST/PSYCHOLOGIST,(I ASSUME HE HAS ONE? IF NOT, HE NEEDS ONE!) ABOUT THE PROBLEM? Follow what the DOC says, giving the advice,at least a month, depending on how severe the problem is! If that doesn't work, try leaving, (temporarily) to see if that changes his attitude. If he changes, then it sounds, to me, like he's just jealous and thinks if he chases you away, he'll have ALL of his father's attention. If he doesn't change, while you're away, temporarily, then you might want to consider making it permanent, 'cause things could REALLY get serious, if you stay! He could start hurting YOUR CHILD, to get at you, then!! But, first, talk to his dad before you do anything and, AT LEAST give HIM a chance to help! If he doesn't then HE HAS NO MORE RESPECT FOR YOU THAN HIS KID DOES, so THAT just might be where the biggest problem lies!!
Good Luck,
