I need to vent

So my husbands friend (a mutual friend he met at our job when we worked together) is recently divorced. He has two kids and they are staying with us. Mind you, I have two of my own and TTC our third. I have to cook and clean and do all the motherly duties for not only my children but his two as well. They leave sometimes to go stay at his friend's apartment. However he can't stay there Mon-Wed because the guy who's on the lease his brother is a sex offender and has to stay there on those days which puts him back at our house. Now, what upsets me the most is he always decides to come over when it's 9pm and I've got everything turned off and shut down in the house. Not to mention his kids are not potty trained they are 3 and 2. They put everything in their mouth, break every toy (a TV has been broken by the dad), even take my kids toys outside and we don't allow them to take inside toys outside. There's so much more that I could add. However I needed a space to talk and vent so I don't keep going off on my husband. Because he says he's tired of me complaining. Well I'm tired of someone taking advantage of us and being disrespectful. Oh to add to it, it's a religious week for us and we are sleeping in tents (remember he hasn't been here all week to celebrate). We have one tent up and he want to arrive tonight at 9pm, text me husband around 8:45 and he reminded him we are in tents, this guy had the nerve to say "is there room for us". We have another tent he could use. However back to being disrespectful he is here at 9pm and now has to build a tent in the dark. I told my husband how rude that was, he goes so you want them in the house. I said no, but why would they start to celebrate now. This guy only cares about what's in it for him and what's most convenient for him and disrespectful to the home owners and my kids. Thank you for listening ❤️
