Want me to come help you kick their immature asses?
They can't stop you from having friends over but, since you share the rent with them sleeping over isn't good unless they do it too.
I had a girlfriend I lived with once. I finally moved out. It was like Grand Central Station there. I couldn't ever get any sleep. Partied every nite and constantly watching my bedroom door at nite lol. You may want to consider a motel to keep the peace until then.
