I'll provide some background for context, but not really sure it's needed. A quick summary would be that last year my wife realized she is not straight. We opened up our marriage. She found a girlfriend that lived about 2.5 hours away. Several months go by, and supposedly the girlfriend's home situation was not super great.

My wife starts finding ways she can move her GF down here. She started fixating on this RV she found on FB Marketplace that was being sold for $14k. She was talking about paying for her GF to rent a place, or take out a home equity loan to use as a down payment to buy a house.

I was getting worried she would do something rash, spend a lot of money, or incur a big debt or something like that. So when she suggested her GF move in with us while she tries to find a job here locally and then figure out what to do from there, I agreed. I feel like this may be important, because it could potentially be construed as "under duress" but I don't really know. I only agreed to her moving in because my wife was not thinking with a rational mind.

The situation has gotten to a point though where it cannot continue. I do not want to get to the point where I tell the GF to either leave or I would call the cops for trespassing, but I will if I have to. But what I don't know is if by staying here for almost 3 months, if she has any kind of tenant rights. There was never any kind of contract or even really a formal agreement of any kind ever established. She still has no job and contributes nothing to the household financially. I don't know if I have a legal right to kick her out (I obviously would not try and prevent her from taking any of her belongings with her.
