I'm not going to say anything after I was insulted by a house guest in my own house.
Well why did you leave then?
I just wanted to get out for a while.
When you go back, I would ask them to leave. You do not have to tolerate house guests if they are rude to you.
I have to tolerate house guests because I invited them to stay in my house.
You don't have to tolerate rude house guests. If someone is disrespecting you especially in your own house then they should leave or apologize.
