I have attempted to take my own life before and he is not stable or sane were he is at. These may be his true feelings or maybe he is trying to push you away out of his own guilt for his actions. I agree he is not the only victim in this. What he did must have hurt you and your son very deeply and you need therapy and attention just as much as him. My only thought is his decision was his and don't blame yourself for his actions. He is the one who tried to take his own life. You can be there for him or leave him but at the end of the day you have to do what is best for you and your son. Take care of yourself and don't forget your pain in all of this. Your pain is just as real as his. I hope you find a way to heal from this and remember his decision is not your fault. It was his bad decision making that lead you to this grief.
