IB, I'm sorry your son gives you a hard time sometimes. He is at a really tough age. Besides all that happened with his father, he is at a crossroads. They dont have the confines of high school and their friends.
They are scared and uncertain. Your son will come back to you one day.
Meantime, set your boundaries and pick your battles.
It is sad your xh has no one. But that was his choice.
Try to get through the next month and then figure out what you want your life to look like.
