My wife invited her friend over our house. My wife and I are both owner of our house. While my wife was out getting food, her friend turned into a psychopath and started cursing up a storm. I told the friend to her face? "Get the fuck out of my house now!" The friend refused to leave. What could I have done that won't get me in trouble with the law and worse, have my ass be in jail?

If I own a gun, could I have use it immediately after the friend refused to leave my house?

If I own a stun gun, could I have use it immediately after the friend refuse to leave the house?

Can I use pepper spray immediately after the friend refuse to leave?

Can I use bear spray immediately after the friend refuse to leave?

Call the police immediately after the friend refused to leave the house. Also leave my house to stay clear of the thread? This last option seem most sensible but also the most pussy thing to do, because after all I am not defending my own home by leaving it.

Thanks.
