In my opinion, which is not an education opinion, I am young and don’t know much about this stuff, I would hope your son will grow up. You don’t owe him a goddamn thing once you die, he is lucky to get anything at all. All of your sons are lucky got get even $5. But, his pain is understandable. There is a lot of hurt from what you have shown in your will. But, he has no reason to act the way he did. If you are truly trying to act in the best interest of your son and not let his mom or anybody take what you are trying to give him away, then that is wonderful. If his mother is really that toxic and cruel, do not give her the opportunity to take advantage of your son. Take the time to explain things to your son, explain your love for all of them and why you are trying to protect them all. Hopefully, as the adult that he should be acting like, he will understand.
