My fiance and I live together with our 4 children. Two months ago, he became very angry with me and in the course of the argument, he punched the wall (subsequently found out he had broken his hand) and then turned on my 9 year old son. Towering over him, he told him in a horribly threatening tone he would kill my son's father if my son ever did a certain behavior again, and then put his hands around my neck and asked my son if he would like for him (my fiance) to choke me. My son was terrified, hiding in the corner, begging him not to hurt us. We left our home for 3 weeks and went to stay with family. I have my son in counseling and am trying to create peace, but I am afraid it will happen again.
Could I file for assault against my son or myself? Is there a statute of limitations?
