<human>: Could you distill the essence of the text into 1-3 sentences?

A few days ago, a friend of mine was in the event horizon of a bad break up. She had posted a simple request on her facebook wall for her ex to STFU and leave her alone.  He didn't like this so he started trash talking her.  In a moment of stupidity I defended her, and put the punk in his place.  Once again he didn't like this, so he got his brother in on it.  His brother said "I will cut you boy" talking to me.  I took this as a threat and went to the police about it.  Its all in the process of review by the Commonwealth Attorney in my area. During all of this I didn't tell my parents, seeing as I'm of legal age I saw no reason to tell them something that would just upset them.  Well today I told them about it, and that the police suggested I get a restraining order.  My mother basically said I should have just let it go and not gone to the police, and went bat shit about the idea of a restraining order.  Was I wrong for going to the police?
<bot>: Got threated to be cut, went to police, told parents, parents went bat-shit over me going to the police.
