Am I right to feel upset?

We offered our home to my husband’s brother and his wife rent free because they couldn’t make rent payments on their apartment after having a massive pay cut. We gave them a 6 month time frame to figure something else out which we thought was more than enough time. However they haven’t even been apartment searching at all and this entire situation has ended up being a nightmare. They stay up until 4am+ making loud noises and music when I have to be up at 6am for my shift at the hospital (I’m a nurse), they leave dirty dishes and trash everywhere even though we have asked them to pick up after themselves, they invite shady people over without asking us first, they smoke pot and cigarettes in our living room and in their bedroom when we have explicitly told them no smoking inside the house and their response is that “they don’t feel like we are making them feel at home if they can’t even smoke inside,” and they look through our private things (I noticed things moved that I know for certain were in a different position). I asked my husband to speak with them about all of this and made a list of everything I’m upset about and told him if he didn’t I will and if they don’t start respecting our home I want them out by the end of the week. My husband spoke to them and his wife started crying saying we aren’t treating them like family should because family should open their home without strings attached or conditions. This sent me over the edge and I told her she has 3 days to pack her things and get out. My husband is now mad at me for saying this. Am I right to be upset?
