Good Morning B., May our Precious Lord give you unlimited peace. B. there is not one thing wrong with allowing your son to live with his father for now. He may actually straighten up. Especially if your Ex is in on what your son has been doing and Not doing. Detentions, Suspensions etc.
It really sounds like he is fighting authority tooth and nail. It can do him good to find and make new friends, new environment, new teachers.
Pray B. he will be willing to straighten up and fly right.
Especially if his dad does the same type of disicpline that you have. "WOW Dad is like mom, I can't get away with anything here either".
Let your little girl know this is only to help her Brother do better in school. It's not because he isn't loved, it's to help him not get in so much trouble at school. As he has made a few wrong decisions, and Mom & Dad have tried helping him, and his teachers are also having a hard time correcting them.
Maybe Daddy can help your brother a little more.
Make it simple, and easy to understand.
Don't allow your son to lay Guilt Trips on you either.
There are reactions to His actions.
Hang in there B., you will be OK and so will your son.
Keep in contact with his dad, with open, honest communication.
God Bless you B.,
K. Nana of 5
