Thank you guys. I will do exactly that, will let the chaos take over. And that's exactly what his bros bf has been doing from start. He keeps himself busy and doesn't help on anything. When I host people in my house I make sure they're well and isn't expect them to clean and cook for me.
This morning they had breakfast, my bf asked me to come down and eat with them (probably they needed someone to wash the dishes after), I jus said that I wasn't hungry. When I finally went down I saw all the dirty pans and plates. I'm not cleaning after their mess anymore.
