.... KNOW this: a child, will always KNOW darn well, when their parent (biological or not) does not like them and resents them and doesn't enjoy them at all.
A child, knows.
This, sets them up, for behavioral problems.
Because, they are never accepted for who they are as a person.
It is very hurtful, for a child's emotions, when they KNOW that their parents do not like them, and is closer with the other kids, instead.
Your son, is also very bright. He is NOT understood... because he is probably on a different set of interests and ways of learning. Which you or the others do not understand.
Thus, he is at a deficit, at home emotionally... because, he has no one in his corner.... nor a soft place to fall.
Your son, is the odd man out... in your family, it seems.
That must be very hard for him.
Very hard, for a young child.
Sometimes, you just have to have a "relationship" WITH your child... it not being based on performance. Just to know and accept a child for who they are. And to have unconditional love etc.
Luckily, your son has not given up... on his academic performance yet. In order to get attention.
Some kids, do that. Out of desperation.
But your son is also as you said, "fussing" all the time.
Well, did anyone simply TALK with him and ask him why????
And, what do you mean by "he makes all the wrong decisions"????
Is he just different from you all, or is he just a bad kid????
There are bad decisions and there are different decisions. It does not mean he is making 'wrong' decisions.
So, discern that difference.
Your son, seems to have no one, who can relate to him. Maybe because he is so bright and outside-the-box, in thinking. That... does not make him "wrong" in thinking or that he is just wrong.
He is different.
Einstein was too. And even though many may have told him he was 'wrong', he was a Genius and made many discoveries, because he was true to himself.
If your son is true to himself, and it is simply because you or others cannot understand him... then that does not make him 'wrong.'
It is because, he just does not think like you all.
Nothing is 'wrong' with that.
Do you know why you are not close to him, anymore, for the past 2 years??? You said you both were inseparable all this time, when it was just you and him for almost 6 years.
Now you have a blended family.
And so, is he lost in the shuffle?
How has he adapted to his new family???
Is he still important, to this family and you???
He does not seem, to be.
He was your 1st child.
And now, he seems to be, the forgotten child or the one who is really feeling.... left out. I imagine.
I really feel bad for him. He must really, be unhappy. And he has no one to turn to. He is, alone.
A child can tell, when their parent(s) don't like them.
Then, they will either stay nice or get hateful toward you too.
They are just a child.
I have a sibling that was disliked by my Mom.
Do you know, that for her entire life... my sibling had LOTS of problems... all because, my Mom, was not bonded very well, to her.
AND, all her life, my sibling BLAMED my Mom. Even if, she admitted that she was a giant pain in the rear.
So, you do something about this NOW.
And create a real relationship with your Son.
Instead of saying you do not like him.
No one in this blended family, seems to like him.
Poor boy.
I think... this blended family... is a hardship for him and it really was not a positive thing for him or an easy thing for him to adjust to.
He probably feels he has no one, and no say, in anything.
And he is right.
He seems to be.... nothing.... and is marginalized in the family.
No wonder, he is fussy.
He must be a very lonely boy, in a big family like this.... 2 siblings and 2 parents.
How sad.
Like he is a 3rd wheel.
