Although it is late in the school year, I urge you to contact the school counselor and your son's teachers to share ideas and to work on a plan to help your son. What are his strengths and potentials? Why is he being suspended? What is going on at school, or on the way to school, that makes him hate school. Talk with your son. What does he like to do? How often have you let him stay home? What limits and consequences have you set up for his behavioral choices?
After talking with the school and your son, I encourage you and your partner to enroll in parenting classes where you will receive support and learn the best ways to set limits for your son.
My response is filled with questions but until you can answer them, it will be difficult for you to find options for your son and for yourself that will establish an atmosphere of trust and safety that he - and all of you -- need to be happy.
