I've never known anyone that I feel could handle this situation as well as you have. Mentally, physically, emotionally....you are amazing. Unusually I have not had to deal with death close to me, for anyone that I cared deeply for.
I can't express my feelings for the person that did this as they are purely negative.
My family is here for you and the little ones any time, no matter what the case.
You are one strong man.
