Ya know what? This situation is your warning.You are very lucky to even GET a warning.Please think for a minute......You say(he explodes...has outbursts of anger.)The "face to face" screaming you mentioned is one breath away from something unthinkable.You were frightened,your friends were frightened....did anyone call the police?This is a reportable offense.One you could be held accountable for as his mother for not reporting it.Then he LIED and CLAIMED your son held a knife when clearly everyone there witnessed your son had NO knife.He further claimed he was defending you.Well,to retrieve a SHOTGUN...he is implying that he felt your very life was in jeapordy.Rediculous!!!!!You say he is "always negative" toward your son.Um...."went overboard with the gun"...??????Are u kidding me? One breath could have made a difference in the existence of your son.YOUR CONCERNS ARE LEGITIMATE!!....I am yelling it from the rooftops!Please....you need to take action.I am so afraid for you and your son and the lengths this man will go to if you attempt to act on this.Let me say...if it was me...I'd pack my shi*...grab my son,and my i.d....and disappear off the face of the earth as far as this man could tell.Because the law isn't so great at protecting you once you say...I am leaving you...and if you stay...you may as well say...this man is more important than my own sons life...because you'd stay by choice...your son has NO choice.If nothing else...put your son somewhere else...in a dif state.He actually needs his mum...ugggghhhhhhhhh I am terrified for him.>.< I am terrified for you.
