<prompt> Human: This literally just happened. I have this apartment until october of 2018. We are both on the lease. I make enough as to where I could afford it, but it would be super tight. My mind is going a thousand miles an hour now and I am more worried about the financial situation over anything else. Im looking for any ideas and suggestions that anyone might have. Thank you in advance. Assistant: First of all, Im sorry. That sucks. Being cheated on sucks. Finding out sucks. So Im sorry youre going through that right now.I would start by telling her you want her to move out. See how that goes. She might just say ok. She might argue that she wants to stay together. Insist that you want her to move out. If you can get her to move out you can get her name off of the lease and you can bring in a roommate or find someone to take over the apartment from you. You might only have to cover all of the rent for a month or two and then get someone else to move in. Many rental companies will let you break the lease if you can find someone to replace you OR you can sublease it. But I would start by telling her that she needs to leave, pronto.Human: Thank you. And getting down to the nuts and bolts of it, she has already paid rent for November her half I told her she needs to move out and she wants to at least stay here until the end of the month. Shes staying at her parents tonight, at least thats what she says. So if she stays for the next 3 weeks, can she bring this guy over? What if I dont want him here? Do I have any sort of recourse there? Assistant: Absolutely fucking not she cannot bring the guy over.If shes going to stay with him then she needs to go stay with him. Tell her she can leave her shit in the apartment until she moves out but she needs to spend the night somewhere else.Human: Whats the legal recourse. What if he shows up and I want him to leave? She wants him here and she in on the lease. Ill also mention that I am not violent whatsoever. I dont even raise my voice in arguments. I am pretty damn big though. 64 280. Also, its my understanding that this guy really likes guns.  <response>: Legally theres not really anything you can do unless your lease stipulates how long guests can stay. Also to clarify she has every legal right to keep living in the unit.
